List of top Physics Questions on Torque on a Current Loop asked in CUET (UG)

Assertion-Reason Type Question Assertion (A): Torque acting on a current loop in a magnetic field is maximum when the plane of the loop is parallel to the magnetic field.
Reason (R): Torque on a magnetic dipole is given by: \[ \tau = MB\sin\theta \] where \(\theta\) is the angle between magnetic moment and magnetic field. Choose the correct answer from the options given below:

A straight wire loop carrying a current \( I \) sits flat inside a uniform, external magnetic field \( \vec{B} \). Under what orientation angle \( \theta \) between the normal vector of the loop surface and the magnetic field lines will the loop experience maximum torque?
