A) Magnet experiences a net torque in clockwise direction and zero net force.
B) Magnet experiences a net force towards left and a net torque in anti-clockwise direction.
C) Magnet experiences a net force towards right and a net torque in anti-clockwise direction.
D) Magnet experiences zero net force and a net torque in anti-clockwise direction.
Correct Answer: C
Solution :
Both the poles of the magnet experience a force due to magnetic field produced by wires \[{{W}_{1}}\] and \[{{W}_{2}}\]. North pole experiences a force \[{{F}_{1}}\] due to \[{{W}_{1}},\] and \[{{F}_{2}}\] due to \[{{W}_{2}}\] as shown in figure. Similarly, south pole experiences a force \[{{F}_{1}}\] due to \[{{W}_{2}}\] and \[{{F}_{2}}\] due to \[{{W}_{1}}\]. From free body diagram of magnet, it is clear that magnet experiences a net force towards right and a torque in anti-clockwise direction.You need to login to perform this action.
