Faraday’s mother-in-Law

4 Faraday's mother-in-Law

Faraday’s Law (ε=-dΦ/dt) implies that a constant magnetic flux results in no induced EMF. EMF is induced only when there is a CHANGE in magnetic flux linkage.

In this comic, the elderly lady is not bothered by extreme temperatures. She is only bothered by CHANGEs in temperature. Haha.
