New cards

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

poles of a magnet

2
New cards

what happens when two magnets are brought close to each other

They exert a force on each other

3
New cards

what is a repulsive, non-contact force

the force exerted if two unlike poles of a magnet are brought near each other

4
New cards

what is an attractive, non-contact force

The force exerted when two unlike poles of a magnet are brought each other.

5
New cards

what is the difference between a permanent magnet and an induced magnet

● A permanent magnet produces its own magnetic field ● An induced magnet becomes magnetic when placed in a magnetic field

6
New cards

What is the force of attraction?

The force caused by induced magnetism.

7
New cards

what happens when an induced magnet is removed from a magnetic filed

the induced magnet loses most/ all of its magnetism

8
New cards

What is a magnetic field?

The region surrounding a magnet where another magnet or magnetic material experiences a non-contact force

9
New cards

give 4 examples of magnetic materials

iron, steel, cobalt, nickel

10
New cards

How does the strength of a magnetic field alter as you move further away from the magnet producing it?

The magnetic field strength decreases the further you move away.

11
New cards

in what direction does a magnetic filed point

-in the direction that a north pole would experience a force if placed in the field. from the north seeking pole to the south seeking pole of a magnet

12
New cards

what does a magnetic compass contain

A small bar magnet that points in the direction of the Earth's magnetic field.
