The current induced in the coil creates another … Webemf = − 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 the change in flux Δ Φ —this is known as Lenz’s law.
