MHT CET 2026 Physics question

If current of 4 A produces magnetic flux of 3 x 10<sup>-3</sup> Wb through a coil of 400 turns, the energy stored in the coil will be

Answer: (B)

The flux linkage is , so the self-inductance is H. The energy stored in the inductor is J, option (B). (Equivalently $U =
