ElectroMagnetic InductionMedium
Question
A negative charge is given to a nonconducting loop and the loop is rotated in the plane of paper about its centre as shown in figure. The magnetic field produced by the ring affects a small magnet placed above the ring in the same plane :
Options
A.the magnetic does not rotate
B.the magnetic rotates clockwise as seen from below
C.the magnet rotates anticlockwise as seen from below
D.no effect on magnet is there
Solution
Loop will act like South pole and act like a magnet thus it try to rotate the magnet in its direction
