Magnetism

When a conductor cuts a magnetic field, a dynamically induced EMF (voltage) is produced in it. Also, magnitude of induced EMF is directly proportional to the rate of change of flux linkages. So this is called Faraday’s law of Electromagnetic Induction. Magnet stationery No current Induces Magnet moving Current Induces The formula for Faraday’s law of … Read more

What is Lenz’s law? Lenz’s law states that the time-varying electromotive force produces a time-varying current, again this current produces EMF or Back EMF. So the polarity of the induced EMF is opposite to the previous time-varying EMF. Lenz law was given by Sir Emil Lenz. This Law decides the direction or polarity of the … Read more
