Question

insulated copper wire in wounder around the plastic cylinder and conncted to galvanometer. what happen why. a) Bar magnet pushed in b) Bar magnet keep our. c) Bar magnet poll. d) Number of terms increases​

Answer 1

$\huge\bold{HEY:)-}$

Science-

Answer :

a)When a bar magnet is pushed inside the coil, an induced current is setup in the coil as the magnetic flux linked with coil changes continuously and galvanometer deflects towards right side.

b) When bar magnet is moving away from coil, as there is changing in magnetic flux linked to coil, induced current is setup and galvanometer deflects in opposite direction.

c) When magnet is held stationary, as there is no change in magnetic flux , the current is not induced and galvanometer will not deflect.

d) if turns increased the magnetic effect will increase as length of wire is directly proportional to magnetic field
