{{#category_index:F|Faraday’s law of induction}} The voltage (in volts) induced in a wire of length (in meters) cutting a magnetic field of strength (in gauss) at the velocity (in m/s) is:

where is the rate of cutting of lines of magnetic flux in maxwell per second and the minus is inserted because of Lenz’s law (q.v.). In vector notation,
