What angle we take between magnetic field and plane of loop....discuss the cases when induced emf is zero in a rotating frame.Ans) We know that Magnetic Flux through a given area is given as ?=B.A= BAcosθLet θ=wt, where w is frequency of sourceNow, the Induced emf will be zero if:1. Magnetic field B is zero,2. Area of the conductor is zero.3. Angle between Magnetic field and Area Vector is 90oAlso the angle between the Magnetic field and plane of loop is taken as anticlockwise angle or positive angle
It is suitable for growing semi-conductively alloys like gallium arsenide. A typical arrangement is furnished with an induction heater that provides a controllable temperature grad
BH curve: For any ferromagnetic material there is a definite value of flux density (B), corresponding to a specified value of magnetising force (H). These values can be ascert
