Question
In an electromagnetic wave the average energy density associated with magnetic field will be(A) $\frac{1}{2} L I^{2}$(B) $\frac{B^{2}}{2 \mu_{0}}$(C) $\frac{1}{2} \mu_{0} B^{2}$(D) $\frac{1}{2} \frac{q}{B^{2}}$
Step 1
Step 1: The energy density of a magnetic field is given by the formula: \[u = \frac{B^{2}}{2 \mu_{0}}\] where \(B\) is the magnetic field strength and \(\mu_{0}\) is the permeability of free space. Show more…
