A square current frame of side a is in a uniform magnetic field B as shown. The net magnetic field at the centre due to the current in the frame has magnitude √3B. Which statements are correct?

Select all that apply

• Option A

  Torque on the frame = 3πa²B²/(2μ₀)

• Option B

  Interaction potential energy is zero

• Option C

  Total field at centre is (√3+1)B if dipole moment is parallel to B

• Option D

  Total field at centre is (√2-1)B if dipole moment is antiparallel to B
