A solenoid having area $A$ and length ' $l$ ' is filled with a material having relative permeability 2. The magnetic energy stored in the solenoid is :

Options:

Answer:

Solution:

$\frac{U}{V} = \frac{B ^{2}}{2 μ _{r} u _{0}} \Rightarrow U = \frac{B ^{2}}{4 μ _{0}} V = \frac{B ^{2}}{4 μ _{0}} A ℓ$
