Task 1
Find out how thee size of the induced current is affected in each of the following cases.(i) The number of turns in the coil is increased.
(ii) The area of the coil is increased.
(iii) A soft-iron core is used.
(iv) A stronger magnet is used.
(v) The coil's speed of rotation is increased.
In all cases, the size of the induced current is increased.
Task 2
Find out how the direction of the induced current changes in each of the following cases.(i) The direction of magnetic field is reversed.
(ii) The coil's direction of rotation is reversed.
In both cases, the direction of the induced current is reversed.
Task 3
Find out how the size of the induced current varies as the coil rotates.
The induced current is zero when the coil is at the vertical position. The induced current gradually increases and reaches a maximum when the coil is at the horizontal position. The induced current decreases to zero as the coil rotates back to the vertical position.
