Compare the strength of the magnetic field near one pole of a bar magnet with the strength of the magnetic field farther away from the magnet?
Magnetic field lines are stronger when closer together.
What happens to the strength of the magnetic field as you move away from a magnet?
When you increase the distance the force is decreased, and when you decrease the distance you increase the force.
The procedure to make a magnetic bell?
You need wire, a nail, and some steel sheet cut from a can. Then you need a bell. Wind the wire round the nail to make an electromagnet. Nail the strip of steel to a wooden block. Fix the electromagnet so that it pulls the steel when switched on. Then you need to make a switch which will be another arrangement of thumbtacks. So when the magnet switches on the steel pulls away from the tack and breaks the circuit. The steel hits the bell but it returns dues tothe magnet being switched off.
When you placed the magnet next to the iron?
nothing will happen dumbazz because it isnt magnetic
Why does a compass spin when it is placed next to a magnet?
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.
Compare the strength of the magnetic field near one pole of a bar magnet with the strength of the magnetic field farther away from the magnet?
Magnetic field lines are stronger when closer together.
Why should video tapes be stored away from magnets and magnetic devices?
Video tapes must be stored away from magnets and other magnetic devices so as not to change the magnetic fields on the small portions of the tape. A magnet or magnetic devices placed near video tapes may be corrupted or data may be deleted.
The strength of electric and magnetic fields remains constant as you move away from the source of the electric and magnetic fields?
yes
How do you control a magnetic field from a distance?
Surrounding a magnet with a magnetic shell can allow the magnetic field to move farther away from its source.
How can you adjust the shake of screen?
Assuming this is for a CRT, sometimes shake is caused by a magnet of some sort including some electrical motors that generate a magnetic field. Try to move away such things as fans or lights. Electricity creates magnetic fields. Trying moving the CRT away from where it sits.
Which direction does magnetic fields flow?
I think it is a mistake to refer to magnetic field 'flowing. Magnetic fields just are, they can change, and these disturbances might move in space, but the field itself does not flow. That being said, and assuming you meant to ask in which direction a magnetic field points the answer is that a magnetic field points towards the south pole of a magnet and away from the north pole. A magnetic field cannot be divergent (i.e. there are no sources) and any field line must be closed.
Can you accelerate a stationary charged particle witha magnetic field or an electric field and please explain?
Yes.You must understand that magnetic fields induce electric fields 90 degrees out of phase (or perpendicular) to them, and vice versa.A charged particle will want to move one way or another when put within an electric / magnetic field, because the field will provide a push or pull on that particle in a specific direction.The easiest physical way to view this is with two magnets - imagine a small stationary magnet. If you take another magnet and hold it close to the stationary magnet, the second magnet will be creating a magnetic field that will either push the stationary magnet away or draw it closer. The same thing can be done by creating an electromagnet (push current through a coil of wire near the stationary magnet).
How do magnetic stripes show Earth's history of magnetic fields?
As you move away from an ocean ridge, the rocks get older.
How can you test if a material is magnetic?
Using a compass; You move the compass around the object and if the hand in the compass goes mad, then it is a magnet To test how something is magnetic: See if it sticks to a magnet. It will only be magnetic if it is made from nickle, iron or cobalt. Steel is also magnetic because it is made mostly from iron. Hope this helps x
How is electricity used to move a car?
Electricity can create magnetic fields. A magnetic field will attract or repel another magnetic field. That principle is used in the manufacture of electric motors. Magnetic fields are created in both an armature and an outside winding. When the magnetic fields are opposite, the armature tries to turn so that it is in line with the outside winding. Then the magnetic field changes polarity and the armature continues in the same direction, pushing the magnetic fields away. The process continues, repeatedly and quite rapidly to make an electric motor armature turn. The armature can be connected to a drive shaft or even directly to a wheel to make the vehicle move.
Where is a bar magnet's pull strongest?
A bar magnet is strongest at its ends, or poles. This is because there is a magnetic field, or B field, that is produced by the magnet itself. The magnetic field can be represented by magnetic field lines, which enter one end of the magnet and exit the other.For instance, in a bar magnet, the magnetic field lines emerge from the north pole of the magnet and enter the magnet at the south pole. Since a magnet has two poles, it is said to be a magnetic dipole.The magnetic field lines are most closely packed together at the poles, since it is a short distance to the opposite pole of the magnet. This is why a bar magnet is most effective at short distances. Picking up a paperclip from a centimeter or two away is much easier than trying to magnetically attract a paperclip to a magnet from a distance greater than five or six centimeters.
What happens to the strength of the magnetic field as you move away from a magnet?
When you increase the distance the force is decreased, and when you decrease the distance you increase the force.
