Question

The energy stored in the magnetic field of asolenoid q0cm

Answer 1

Answer:

Explanation:Magnetic field,B of a long solenoid is given by (mu)*n*I ; where mu-permeability of free space,n-no. of turns per unit length of the solenoid,I-current through thr solenoid. magnetic dipole moment,m of the solenoid is given bu I*area of it. Energy= - (dot product of m and B).

please state the question clearly especially q0cm.
