1. Description
The solenoid can be used to magnetize and
demagnetize ordinary magnets or iron bars in
addition to conducting inductance experiments.
The rugged unit consists of a coil with insulated
copper windings mounted on a base plate with 4 mm
sockets and a switch.

4. Sample experiments
4.1 Demagnetising
•
Put the sample to demagnetize inside the coil.
•
Connect the coil to the power supply and apply a
voltage of 12 V AC.
•
Switch on the coil and wait for a short while.
•
Slowly decrease the voltage to zero and then pull
the sample from the coil.
The sample should then be demagnetised.
