WebThe equation for the emf induced by a change in magnetic flux is. emf = − N Δ Φ Δ t. 23.2. This relationship is known as Faraday’s law of induction. The units for emf are volts, as is usual. The minus sign in Faraday’s law of induction is very important. The minus means that the emf creates a current I and magnetic field B that oppose ...
