Making a Magnet

• By stroking

(i) Single touch method

(ii) Double touch method is a better method

• Electrically

Place magnetic material in a solenoid (cylindrical coil of wire) which is connected to 6-12 V d.c. supply. Switch on current for a second and then off. Remove material from solenoid - material will be a magnet.
Polarity of magnet produced depends on direction of the current -
Right Hand Grip Rule
= if the right hand grips the solenoid - place
fingers on one by one in the direction of the
current - (positive to negative) the thumb
points to the north pole.
