Permanent and Induced Magnetism

At which part of a magnet are the magnetic forces strongest?

The poles.

What happens when two magnets are brought close to each other?

They exert a force on each other

What type of force is exerted if two like poles are brought near?

A repulsive, non-contact force.

What type of force is exerted if two unlike poles are brought near?

An attractive, non-contact force.

What is the difference between a permanent magnet and an induced magnet?

Permanent magnet makes its own field; induced magnet only in a field.

What type of force does induced magnetism always cause?

A force of attraction.

What happens when an induced magnet is removed from a magnetic field?

It loses most or all magnetism.

What is a magnetic field?

The region where a magnet/magnetic material experiences a force.

Give four examples of magnetic materials

Iron, Steel, Cobalt, Nickel.

What can always be said about the force between a magnet and a magnetic material?

It is always attractive.

How does the strength of a magnetic field change as you move away from the magnet?

It decreases with distance.

In what direction does a magnetic field point?

From north pole to south pole.

What does a magnetic compass contain?

A small bar magnet that aligns with Earth’s field.
