How does a compass needle respond when a compass is placed with in a magnetic field?
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
A flowing current is surrounded by magnetic fields. The compass needle reacts to those, since that's what a (magnetic) compass does.
A compass needle may spin in a circular direction either right or left when it is placed in a magnetic field. It can also pull to the side that the magnetic field is most prominent on.
A compass needle, as well as everything else on Earth, is ALWAYS within a magnetic field. If the compass needle is free to turn, it will align itself with the magnetic field, and point along the north/south axis of the field. If another magnetic field source appears near the compass ... such as a current-carrying electrical conductor, or a toy magnet in somebody's pocket ... whose field strength is comparable to the Earth's, then the… Read More
The same direction as a compass needle would point when placed in the magnetic field.
The magnetic field created by the current in the wire deflects the compass needle.
Compass needles don't point north when a magnet is near it. Rather, a compass needle will point to the magnetic north when a magnet is NOT placed near the compass. This is because the needle of a compass is a magnet balanced on a pivot that allows the needle to move. The needle, in turn aligns itself with the magnetic field of the earth, and as a result, one end of the magnet (the needle)… Read More
In a regular magnetic compass, the needle is a magnet. One end is the south pole and the other end is the north pole. Magnets are affected by other magnets. If a magnet is placed near a magnetic compass, the north pole of the compass's needle is attracted by the south pole of the magnet, and the south pole of the compass's needle is attracted by the north pole of the magnet.
To find where is someone placed, based on the compass' needle, which is always pointing to the magnetic pole of the Earth, that is the North. That provides orientation to the person since he has a map along with him.
The direction of a magnetic field is defined by the direction in which a compass needle will point when placed within that field -that is, from north to south.
When a compass pointing north will point in a different direction when placed near a piece of metal Which causes this to happen?
The needle in compasses is magnetic and is drawn to the Earth's magneticism in the North. When the needle is placed near a metal, as all magnets are, attracted to metals.
True... The wire carring current creates a slight magnetic field.
Instead of being attracted by the magnetic field of the earth, it is being attracted by the magnetic field of the current carrying wire.
What will be deflection in compass needle of a magnet when a current carrying wire is placed over it?
The compass needle will turn until it's perpendicular to the wire, provided the current in the wire is enough to generate a magnetic field around the wire that's strong enough to swamp out the effects of the Earth's magnetic field. (That doesn't take much current.)
When a compass is placed near a conductor where current flows its needle would deflect what does this indicate?
This proves that a magnetic field is developed around the conductor wen current flows through it...
The Compass needle not points towards north when placed near iron objects or any magnetic substance(an object which is attracted by a magnet). Edit; Apart from the above, the molten core of the Earth induces circulating currents that place the North Magnetic Pole in Canada and not at the Geographic North Pole; and for that matter the South Pole similarly. It is both intriguing and fortunate that the Geographic and Magnetic Poles are so close… Read More
You would need a piece of cork or other soft floating material, perhaps polystyrene, also a needle and a magnet. stroke the needle with the magnet a few times in the same direction and them insert the needle into the floater so that it is horizontal when the floater is placed in water, place floater into a container of water, the needle will point toward the magnetic north.
No. The true north pole and the magnetic north pole are in different locations. The compass will point at the magnetic north pole. If you happened to be somewhere between the two north poles, the compass will point exactly backwards!
Current flowing through a wire induces a magnetic field, causing the compass to point away from "magnetic north" and point in a different direction.
How could you find out the shape of the magnetic field when two bar magnets are close to each other?
You can cover the magnets with paper and scatter iron filings on the paper. Tap it gently and the filings should take up the pattern of the magnetic field. Alternatively, a tiny compass called a plotting compass can be repeatedly placed in the area around the magnets and the position of the needle marked each time. This is more tedious but less messy, and can also show you the direction of the lines of force.
Magnetic north is negative and magnetic south is positive. The resulting magnetic field lines go from north to south. Mnemonic: north = negative. Answer The terms, 'positive' and 'negative', are generally applied to electric charges, not to magnetic poles. Having said that, 'magnetic therapists' use the terms 'positive' and 'negative' when referring to magnetic poles -however, their knowledge of magnetism appears very shaky! Magnetic poles are normally identified as 'north' and 'south'. The 'direction' of… Read More
A current wire deflects a magnetic needle placed near it because the current wire is creating an electric field. If the current is supplied from an AC (alternating current source as opposed to DC which is direct current- AC would be from a wall socket, DC from a battery), then the current is constantly changing, so the electric field is constantly changing. A changing electric field results in a magnetic field perpendicular (90 degrees) to… Read More
Cork can be used in a lot of ways. Because it floats a magnetized needle placed on top of a piece of cork will act as a compass. This simple device can also respond to a permanent magnet and show action at a distance. Cork can also be used to seal a flask against low pressure leakage.
We can draw a magnetic field by placing a compass around the magnet at various locations and drawing points with the help of a pencil on the paper at which this apparatus is placed. After drawing points we can join them and this gives the magnetic lines of force, which constitute the magnetic field.
A magnetic field exists in the space surrounding a current-carrying conductor. (Ampere's law). At the point in space where the compass sits, if the strength of the fields due to electrical conductors in the vicinity is a significant fraction of the strength of the earth's magnetic field, then the compass reading is guaranteed inaccurate.
Its an experiment initially. So basically, if you have a compass placed ABOVE a wire with current passing through it, you can use a form of the right-hand rule to determine which way the compass will point. So there are two ways to use the right-hand rule: * Where you point your thumb in the direction of the current flow, and use your other fingers to see which way the magnetic field is. * Where… Read More
Field Lines Show Magnitude and Direction When the lines of the magnetic field are close together the magnetic field is strong. In a region where the line density is high, one says that it has great intensity or strength. Technically, the density of lines is proportional to the magnitude of the field. The direction that magnetic field line are oriented provides the information on the direction of the field, with the convention that the lines… Read More
Any magnet will always align itself to north south direction of earths magnetic field. Magnetic needle will always be perpendicular to the direction of current. Stronger magnets attracts weak magnets towards itself if the weak magnet is placed in stronger magnets magnetic field.
Magnets have magnetic fields that attract items containing iron. Some of the substances attracted to magnets include iron, nickel, and steel. To understand a magnet you must first understand the magnetic field. A magnetic field is created as the result of moving charges such as electrons. A magnet's magnetic field either attracts or repels certain metals, as well as other magnets. A magnet has two ends that are referred to as poles. One pole is… Read More
galvanometer is invented by Lewis galvany .In galvanometer is an electrical device which is used to deteced electric current in a circuit consist of a rectangular coil which placed in magnetic Field such that a needle is connected to that coil.
yes. when a coil or wire is hooked up to a power source the wire creates a magnetic field. since a battery's current travels from - to + and a magnet travels from north or - to south or + therefore the magnetic current SHOULD travle from the part of the wire connected to the negative to the part connected to the positive Further Answer Viewed from either end of a straight conductor, the magnetic… Read More
Magnets and iron. A compass has a needle that has a magnatized end. If there are outside objects near then it will give a false reading. I have placed a knofe in the console before and had my compass read 20 degrees off. If this had gone undetected the results could have been the difference between running aground or getting lost or getting where I wanted to go. Car keys will do the same thing.
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
the magnet in the compass will point to the wires magnet.
How can a change in voltage in a coil of wire be transferred to a neighboring coil of wire without physical contact?
When electric current flows through a coil of wire it generates a magnetic field. Variable current generates variable magnetic field. When a second coil is placed in a variable magnetic field of the first one an electric current is generated in it. Magnetic nature of the connection between two coils can be proved by the fact that it takes place only when the second coil is aligned with the magnetic field of the first one… Read More
Which test can best detect the presence of electrical current a the needle of a compass b the bulb in an electric circuit blows c the plug of an iron is placed in the socket?
Here are some possible answers: a) If you hold a compass close to a wire you may see the needle move. How much it moves depends on the strength of the current flowing in the wire. If the needle doesn't move then there may be three explanations: 1) No direct current was flowing in the wire OR 2) a direct current was flowing but it was too weak to make the compass needle move OR… Read More
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
Electric current produce magnetic fields. However, in the case of AC (alternating current, usual in households), the current changes so quickly (and the current has an average value of zero) that I am not sure the effect on a compass would be visible to the naked eye.

The magnetic flux through any surface placed in a magnetic field is the total number of magnetic lines of force crossing this surface normally
the arrow goes to the magnet
Hungary is placed in the north-west of Romania.
My child placed 4 magnets on 4 sides of a compass and now its not giving proper direction it is giving opposite direction. Any solutions to correct it please?
The simple solution is to 'stroke' the NORTH pole of a bar magnet along the needle from north to south - about 30 strokes should do it.
Nowadays, a compass is an instrument containing a freely suspended magnetic needle which points to the earth's magnetic north. But how did it all start? To find out, we have to travel as far back as 220BC....... I am afriad of bananas. In about 220BC, the Qin dynasty (221 - 206BC) had just started, and this is when the most basic compass was probably made. Fortune tellers used lodestones, which aligned themselves in a north-south… Read More
the particles in the non magnetic material get magnetised, therefore it temporarily becomes a magnetic.
Uh, no. Their are three kinds of norths you normally deal with. There is magnetic north, this is where a compass points towards. There is grid north. This is where a map, which is only a representation of the earth's surface drawn to scale and placed on a flat surface, tells you where north is. And last but not least and not the same as either one of the previous two is true north. The… Read More

yes magnetic fields can be broken if the magnetic keeper is not placed between the poles and it would also stop the flow of magnet
They all end up going in different directions so that it is magnetic anymore.
Does a magnetic field have an effect on a capacitor when it is placed between the plates? Yes, a magnetic field between the plates of a capacitor would have some effect. Without more information it is difficult to determine how much.
for this you need an iron pin, a magnet and a plastic cap that can float on water. Magnetize the iron pin by rubbing a magnet on it continuously in one direction for about 15 minutes. Now place the needle in the centre of the plastic cap and hold it in position with cello tape. take a container containing water and put the cap in it such that it floats on it. The pin will… Read More
