ElectroMagnetic InductionHard
Question
An infinite current carrying wire passes through point O and in perpendicular to the plane containing a current carrying loop ABCD as shown in the figure. Choose the correct option (s).
Options
A.Net force on the loop is zero.
B.Net torque on the loop is zero.
C.As seen from O, the loop rotates clockwise.
D.As seen from O, the loop rotates anticlockwise
Solution
Magnetic force on wire BC would be perpendicular to the plane of the loop along the outward direction and on wire DA the magnetic force would be along the inward normal, so net force on the wire loop is zero and torque on the loop would be along the clockwise sense as seen from O.
