Question

1. What effects do you expect on passing current through a conductor?
2.How it can be shown that a current carrying conductor produces a magnetic field?

Answer 1

It produces heat and some magnetic effect and it can be shown by bringing iron nails near it

Answer 2

1. Two effects could be expected
Heating effect
Magnetic effect
2. Make a circuit and pace a compass near it. Now, when you will close the curuit and make the currents pace a flow you will obsere that the neddle of the compass is getting deflected.

This prooves that the flowing current through a conductor have magnetic effect.
