BRAINCAKEFaraday's Law of Electromagnetic Induction
The Magnetic flux Φ passing through a given area A is the product of the magnetic field density B and the area it passes through. Φ = BA. The magnetic flux than links a coil of N turns is called the magnetic flux linkage and is given by NΦ or NBA. The unit is the weber (Wb)
