In magnetism, we find Electromagnets (solenoid, toroid, etc), Permanent magnets. These provide a magnetic field around them.
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. If the flux is time In-varying in nature, additionally it requires relative motion between … 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
