In an induction coil the secondary e.m.f. is
Webv. t. e. In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, [1] [2] denoted or ) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf [3] by converting other forms of energy into electrical energy. [3] WebEMF Inducted in a Rotating Coil. When a coil rotates in a uniform magnetic field, the flux through the coil will vary as it rotates; Since e.m.f is the rate of change of flux linkage, this means the e.m.f will also change as it rotates . The maximum e.m.f is when the coil cuts through the most field lines; The e.m.f induced is an alternating voltage; The maximum …

WebIn an induction coil, the secondary e.m.f. is A Zero during break of the circuit B Very high during make of the circuit C Zero during make of the circuit D Very high during break of … WebFaraday's law of induction. We'll move from the qualitative investigation of induced emf to the quantitative picture. As we have learned, an emf can be induced in a coil if the magnetic flux through the coil is changed. It also makes a difference how fast the change is; a quick change induces more emf than a gradual change.
WebThe mutual inductance between two coils is 1.25 henry. If the current in the primary coil changes at a rate of 80 ampere/second, then the induced e.m.f. in the secondary coil is Q.
