Question

energy of soleonide​

Answer 1

$\huge\mathcal\red{Answer}$

Magnetic Field Created By A Solenoid: Magnetic field created by a solenoid (cross-sectional view) described using field lines. Energy is “stored” in the magnetic field. ... Therefore, the energy density uB=energy/volume u B = energy / volume of a magnetic field B is written as uB=B22μ u B = B 2 2 μ .
