Physics Question on Current electricity
A cylindrical bar magnet is kept along the axis of a-circular coil. If the magnet is rotated about its axis, passing through the centre, perpendicular to the face, then:
A
a current will be induced in the coil
B
no current will be induced in the coil
C
an emf and a current both will be induced in the coil
D
none of these
Answer
no current will be induced in the coil
Explanation
Solution
If the magnet is rotated about its axis, passing through the centre, perpendicular to the face, then there will be no change in the magnetic flux linked with coil, so, no current will be induced in the coil.
