Question 11.

Why is magnetic compass needed to test the conduction of electric current?

Answer:

Sometimes, when the current passing through a conductor is so small that filament of the bulb does not get heated up and the bulb does not glow. In this case, we need magnetic compass to test the conduction of current.
