A current loop of area and carrying a current of is held parallel to a magnetic field of intensity . The torque in acting on the loop is:
Step 1: Given data
Area of the current loop,
Electric current flowing in the current loop,
Magnetic field intensity,
Angle between the current loop and the magnetic field,
Torque acting on the current loop,
Step 2: Formula used
………………….(a)
Step 3: Calculation of the torque acting on the current-carrying loop
Substituting the given values in equation (a), we get
Hence, option (a) is correct.
