A single circular loop of wire with radius 0.02 m carries a current of 8.0 A. It is placed at the centre of a long solenoid that has length 0.65m, radius 0.080 m and 1300 turns. (Axis of circular loop coincide with axis of solenoid). Let 'i' be the current in solenoid.

Select all that apply

• Option A

  If i = 100 mA, the magnetic field at the center of coil can be zero.

• Option B

  If i = 44 mA, the magnetic field at the center of coil can be zero.

• Option C

  If i = 100 mA, the magnetic field at the center of coil can be 8π × 10⁻⁵ T.

• Option D

  If i = 100 mA, the magnetic field at the center of coil can be 16π × 10⁻⁵ T.
