Does radius increase induction of a coil
WebMay 6, 2015 · Consider an imaginary disk whose normal vector is parallel to the axis of the coil and which is inside the coil. If you integrate this equation over the area of that disk you get [ a] E = − Φ ˙. where Φ is the flux threading the disk and E is the EMF drop around the loop. This is called Faraday's law. WebIn such a circuit, increasing the number of turns in the coil would increase resistance by the same factor and the magnetic field would stay the same. But most circuits are not …

Web(i) W ith the increase in the distance between the coils, the magnetic flux marked with the stationary coil decrease and hence the mutual inductance of the two coils will decrease. (ii) M ∝ n 1 n 2 so with the increase in … WebWhen the coil is rotated, it ‘cuts’ through the flux, or field lines and an e.m.f. is induced. The size, or magnitude, of the induced e.m.f. depends on: the amount of flux through the coil; the speed of rotation; the number of turns on the coil. Each turn on the coil has a flux linkage which changes as the coil rotates.
