Magnetic field due to currentHard
Question
A current - carrying ring is placed in a magnetic field. The direction of the direction of the field is perpendicular to the plane of the ring -
Options
A.there is no net force on the ring.
B.The ring will tend to expand.
C.The ring will tend to contract.
D.Either (B) or (C) depending on the directions of the current of the current in the and the magnetic field.
Solution
net force = 0 and ring will tend to expend /contracts depending on I & B.
