Induced current and magnetic flux

Web29 okt. 2024 · Electric current is only induced in a coil of wire if the magnetic field is moving relative to the coil. Faraday's Law gives the electromotive force (emf) ε produced in a coil by a magnetic field: In other words, the emf (electric potential) induced in the coil is proportional to the rate of change of flux linkage. WebThe magnetic flux and voltage is directly proportional to each other. The formula for the magnitude of the magnetic field can be written as, B = \frac {\mu_0I} {2\pi r} ….eqn (1) In …
