You move a bar magnet two inches through a coil of wire. what do you observe in a galvanometer hooked up to the coil?
the pointer moves one direction and then goes back to center.

the pointer does not move.

the pointer moves one direction and then stops in that position.

the pointer swings one way and then swings the other way.

The correct option is (a).

Explanation :

The galvanometer is a device which is used to detect the flow of current in the circuit. On the application of electric current in the circuit, the needle of galvanometer deflects.

It is given that, a bar magnet is moved two inches through a coil of wire. The current will produced in the coil due to the magnetic field.

As there is no change in the magnetic field, the pointer moves in one direction and then goes to back to center.

Hence, the correct option is (a) " The pointer moves one direction and then goes back to center".

c. 75.7

i think that is the right

what does the table look like
