Question

Example 6.10 obtain the expression for the magnetic energy stores
in a scend in terms of magnetic field Bares A and length of the
solenoid. by How does this magnetic energy compare with the
electrostatic energy stored in a capacitor?​

Answer 1

Answer:

Therefore, the magnetic energy stored in a solenoid in terms of magnetic field B, area A and length l of the solenoid is 12B2μ∘×Al which is the correct answer.
