Question

You can get a light bulb to light three different ways. What are they??

Answer 1

Yes, we can produce light in three different ways.

(1) By connecting the bulb for two terminal of battery

(2) Through electric current: By connect light blub into a socket.

(3) By the process of mutual induction:

[ Key point: he change in magnetic flux produces the induced current.]

consider a circuit prepared with many loops connected to a light bulb. Place a magnet inside the loop. If loop is stationary, then there no induction of current takesplace in the loop. If same loop in a field that is changing in time produces electromotive force, hence the bulb glows.
