Task 1
How is the induced current affected if(i) the polarity of the magnet is reversed.
(ii) a stronger magnet is used.
(i) The direction of the induced current is reversed.
(ii) The induced current becomes larger.
Task 2
How is the induced current affected if a coil of(i) more number of turns; and
(ii) a large area.
is used?
(i) The induced current becomes larger.
(ii) The induced current becomes larger.
Task 3
Insert a soft-iron core into the coil. How is the induced current affected?The induced current becomes larger.
Task 4
What is the effect on the induced current if(i) The coil rotates at a higher rate; and
(ii) the direction of rotation of the coil is reversed?
(i) The induced current becomes larger.
(ii) The direction of the induced current is reversed.
Task 5
Determine the orientation of the coil when the induced current is(i) the largest; and
(ii) the smallest.
(i) The induced current is the largest when the coil is at the horizontal position.
(ii) The induced current is the smallest when the coil is at the vertical position.
