Why a freely suspended magnet comes to rest in north south direction?
It reacts to the magnetic field of the Earth.
If earth's magentic field is like a bar magnet where is the north pole of bar the magnet?
If we were to align a bar magnet with the Earth's magnetic field the north pole on the bar magnet would be the red-colored portion. When it comes to Earth, as of now the North pole is in the arctic. However, this is the magnetic north pole which is slightly off true north and always wandering due to variations in the Earth's magnetic field. True north is exactly what the name implies, it the very top and perfectly centered point on the Northern hemisphere.
Why is the earth's magnetic north pole really a magnetic south pole?
The north pole of a magnet is defined as that pole which is attracted to the Earth's magnetic pole. Since opposite poles attract that would, indeed, make the Earth's Northern hemisphere pole a magnetic south pole.Another AnswerLet's start by sorting out the terminology. 'Magnetic North' is a location, so-called, to distinguish it from 'True North'. It is not the magnetic polarity of that location. Magnetic North is not a fixed location, but is always moving relative to Magnetic North which is located at the earth's axis.A freely-suspended magnet, when it comes to rest, essentially points towards Magnetic North (it actually lies along the lines of magnetic flux that join Magnetic North and Magnetic South). For this reason, that end of a magnet (and that of a compass needle) was originally called its 'North-seeking' pole. Over time, we have dropped the word, 'seeking', and it's now simply called its 'north pole' and, by common agreement, this is also considered to be its magnetic polarity.So, if the 'north' pole of a magnet points towards the location we call 'Magnetic North', then the magnetic polarity of that location is a south pole. This is because unlike poles attract.So, to answer the question, the south magnetic pole of the earth is located (deep within the earth) below the located we call 'Magnetic North' in Canada.Why people find this so confusing can only be put down to poor teachers!Read more: Where_is_the_south_magnetic_pole_of_the_earth
What divides the globe into units called poles?
No. Each of the two 'poles' is a definite place ... a point on the surface of the earth. The earth is spinning, once every 24 hours (which is the reason we have day and night). If you picture the earth as a spinning basketball, you can imagine a giant pencil stuck through it that it spins on. The places where the giant pencil goes into the ball and comes out of the ball are the poles. If there was no spin, there wouldn't be any poles. The location of the north pole is 90 degrees north latitude. The location of the south pole is 90 degrees south latitude.
What are the advantages and disadvantages of a bar magnet?
A bar magnet, like other magnets, has uses based on its magnetic attraction. This magnetic attraction draws other ferromagnetic materials to it or the bar magnet towards them. These uses include: picking up small ferromagnetic items such as screws and metal shavings; being used as "magnetic stirring rods" on laboratory hotplates; and holding papers and other items to the sides of refrigerators. Like other magnets, the magnetic field generated by a bar magnet can damage electronic equipment. A bar magnet placed near a hard drive, computer disk, or even a video cassette can cause the data stored by the magnetic particles on the item to be damaged. Bar magnets placed on the sides of speakers or other sound devices can cause disruptions in the sound or even permanent damage. A bar magnet placed on the side of a computer can result in the system being deactivated, and may even make it completely inoperable.
When a magnet is freely suspended what suspended what position you will find the magnet in when it comes to rest?
When the magnet is free to rotate and its poles are in a horizontal plane, it comes to rest with its poles pointing roughly north and south.
How do you detect the poles of a magnet using compass?
To identify the north pole of a magnet, make a compass out of it by hanging it on a string or floating it on water. The pole that faces geographic north is the north pole. Once you have a magnets poles labelled, you can use it to identify orientation and poles on another magnet since like poles repel and opposite poles attract.Alternative AnswerEasier still, use a compass! A compass always points to the south magnetic pole of a magnet.
What is The part of a magnet that points north is called?
The pole of the magnet that points to earth's magnetic north is the south pole of the magnetIt should be understood that the north pointing end of a compass is a North magnetic pole. That being so, the north pole of the earth got its name because of this fact. Actually, the north pole of the earth has a South magnetic polarity which attracts the north pole of the compass. The south pole of a magnet points to the south pole of the earth because the south pole has a north magnetic polarity. Confused? Just remember that true (magnetic) north resides in the magnet; not in the earth. dbm 7/16/09Clearer AnswerThe above answer is incorrect. The poles of a magnet were named after the directions in which they point. The earth's poles were NOT named after a magnet's poles!When a horizontally-suspended comes to rest, it points in an approximately North-South direction. For this reason, the end of the magnet pointing North was called the 'North-Seeking' pole, and the other end was called its 'South-Seeking' pole. We no longer use the terms 'seeking', and we now call the ends of a magnet its 'north pole' and 'south pole' and these terms are also used to define their magnetic polarities.To differentiate it from True North and True South, we say that the magnet actually points to Magnetic North and Magnetic South -these are the names given to directions (or location) NOT their magnetic polarities. So, because 'unlike poles attract', the magnetic polarity at the location we call 'Magnetic North' is a south pole which therefore attracts the north pole of a magnet.
What poles attract and what poles repel?
poles of the same kind repel one another. poles of differet kinds attract, and this is where the saying ' opposites attract' comes from.
Why do magnets sticks with another magnet?
Magnets are composed of various materials. These include iron, cobalt, nickel, and some rare earth elements. Naturally occurring magnets are called lodestones. A magnet often has two poles refered to as the North and South poles. These poles may be located in a variety of positions such as near the ends, on opposite faces, or even on the edges of a magnet. Oppositly charged poles attract each other. Magnetism is seen whenever electrically charged particles are in motion. This comes from the movement of electrons in an electric current, resulting in electromagnetism, or from the quantum-mechanical spin and orbital motion of electrons, resulting in what are known as permanent magnets.
Where did magnetite get its name?
If a bar magnet were suspended, and allowed to come to rest, it would point in an approximately North-South direction. The end of the magnet that points towards the North was originally called the 'north-seeking pole', and the end that points towards the South was originally called the 'south-seeking pole'. Over time, we have dropped the use of the word, 'seeking', and now simply refer to them as the magnet's 'north' and 'south' poles which describe their magnetic polarities. Magnets don't actually point in the direction of True North and True South (located at the earth's axis of rotation) but, rather, at Magnetic North and Magnetic South, which are locations that 'wobble' around True North and True South. Because of this, navigators have to allow for the difference between Magnetic North and True North in order to accurately plot a route. Magnetic North does not refer to magnetic polarity, but is used to differentiate its location from that of True North. Because 'unlike poles attract', the polarity of the location we call Magnetic North is a south magnetic pole -which is why the location attracts the north pole of a magnet or compass needle.
Why is a nail attracted to a magnet?
The nail is made of non-polarized iron. and doesn't repel either side of a magnet. A magnet has two poles and will repel another magnet with the same pole (north repels north, south repels south). Since the nail doesn't have a poles it doesn't repel either side.
Why does a compost attract to a north magnetic and repel by the south?
OK- first, it is a compass. The needle of a compass is a magnet. It points to the Eath's Magnetic Poles- the two spots where the Earth's magnetic field comes out of the ground. In magnetism, opposites attract, likes repel.
Does a magnetic field exist only at a magnet's poles?
No. A magnet with one pole is not a magnet. If you cut a bar magnet in half, both of the newly exposed ends would be north and south respectively (if you did not demagnetise the magnet in the process). The magnetic circuit must be completed, one way or another, always. Try the experiment of placing a magnet under a sheet of paper and then sprinkling iron filings onto the paper. The iron filings will always take on the shape of the magnets magnetic field, the lines of force. It does not matter what you do to the magnet, you will never get rid of one of the poles. Then there is the argument about the theoretical spherical magnet - where are the poles?No because then it isn't a magnet and other materials might not stick to the north pole of the magnet
Is there water on mars for us to live?
There are South and North Poles but there is no water as it comes in the form of gas.
Why a freely suspended magnet comes to rest in north south direction?
It reacts to the magnetic field of the Earth.
How do magnets attract and repel each other?
Not only magnets, but metal repel. There are two kinds of charges that metal contain, positive and negative. If you push a positively-charged magnet towards another positively-charged magnet, they'll repel, maybe because one type of charge needs the other to attract. If this one type of charge comes close to another charge of the same kind, it won't receive what it needs, and feel "resent" to the other charge, then repel. If you push a negatively-charged magnet towards another negatively-charged magnet, they will also repel.
