Question

with the help of labelled circuit diagram describe an activity to illutrate the pattern of of the magnetic field line around a straight current carrying long conducting wire

Answer 1

Aim of the experiment:to show current carrying conductor produces magnetic feild.

Material required:battery,wire,switch,iron fillings,cardboard.

Procedure:

1.make an simple circuit .

2.insert a wire in the carboard ,then connect with the circuit.

3.sprinkle some iron fillings in the cardboard.

4.on the switch of the circuit

Observation:you would see the circular magentic feild around the cardborad.
