i)

Magnetic field is the area around a magnet where the effect of the force of a magnet can be felt/experienced.

ii)

Methods of making magnets

1. Hammering/strong heating in the earth's magnetic field
2. Stroking
3. Electrical
4. Induction

i)

Electromagnetism is the production of a magnet by the use of electric current.

ii)

The key is switched on and off few times. When the pin is removed and tested, it is found to be magnetized.

(i)

Appliances which use electromagnets in their operation

1. Telephone receivers
2. Loudspeakers
3. Electric bells
4. Burglar alarms
5. Microphones

(ii)

Ways in which a magnet can lose its magnetism

1. Heating the magnet in fire
2. Striking the magnet continuously with a hammer
3. Placing it in a solenoid through which an alternating current flows

(i)

Magnetic pole

Point/area on a magnet where the magnetic force is greatest or where all lines of force appear to enter.

(ii)

Uses of temporary magnets

1. Loudspeaker
2. Electric bell
3. Telephone earpiece
4. Generators/electric motors
