Aim: To create a tester to test conduction based on magnetic effect of electric current.
What you need: A compass, 2 copper wire, A battery and 1 led.
Process: Connect the wires to the led and battery together. Now get the compass and put it near the circuit. What do you observe?
Observation: You will see that the needle in the compass starts to deflect to the opposite side. This proves that there is a magnetic field around the circuit which causes the needle of the compass.
