Question

how can the magnitude of current induced ina coil be increased by using coil and bar magnet method?​

Answer 1

Answer:

If additional layers of wire are wound upon the same coil with the same current flowing through them, the static magnetic field strength would be increased. ... By moving this bar magnet “in” and “out” of the coil a current would be induced into the coil by the physical movement of the magnetic flux inside it.

Answer 2

Answer:

:- The magnitude of the induced current can be increased by: Taking the conductor in the form of a coil of many turns of insulated wire. Increasing the strength of the magnetic field used. Increasing the rate of change of magnetic flux associated with the coil.

:- The deflection increases when the current is increased because the magnitude of the field is directly proportional to the strength of the electric current. That is, stronger the electric field, stronger the magnetic field.

:- If additional layers of wire are wound upon the same coil with the same current flowing through them, the static magnetic field strength would be increased. ... By moving this bar magnet “in” and “out” of the coil a current would be induced into the coil by the physical movement of the magnetic flux inside it.
