The time-varying magnetic field is produced by a changing current, and the behaviour of the capacitor is based on the properties of the electrical field created in a non-conductor that is placed between two conductors. In other words, the capacitor is a non-conductor sandwiched between two conductors. Energy isn''t generated by an inductor or

Mutual inductance is the effect of two devices inducing emfs in each other. A change in current dI1/dt d I 1 / d t in one circuit induces an emf ( ε2 ε 2) in the second: ε2 = −MdI1 dt ε 2 = − M d I 1 d t, where M is defined to be the mutual inductance between the two circuits and the minus sign is due to Lenz''s law.
