JEE Class main Answered
find the energy in the magnetic field if current of 5A produces a magnetic flux of 2*10^-3 Wb through a coil 500 turns.

Expert Answer
Energy = (1/2) L i2
inductance L isdefined as, L = n Φ / i , where n is number of turns, Φ is flux and i is current in the coil.
hence energy = (1/2) n Φ i = (1/2)×500×2×10-3 × 5 = 2.5 J
