WebThe magnetic field intensity (H-field) is how the B-field exists within a magnetic material (such a magnet). The H-field is given by: H = B/mu + M H = magnetic field intensity (in SI units of A/m or cgs units of Oersteds (Oe)) B = magnetic flux density (in SI units of Tesla (T) or cgs units of Gauss) mu = permeability of the magnetic material WebThe magnetic field induced by the current that is induced, or that current that's being caused by the electromotive force and the magnitude of the force is going to be dependent on our resistance, that's going to go in the other direction, it's going to go down that way. Or it's going to induce a magnetic field that is gonna go downwards.

"WebOnce it gets going, Lenz' law says it will create a back EMF that will oppose the original. The sum of that back EMF and the original lead to a lower total voltage to the motor once it reaches speed, and less current flowing through the motor, and then the lights get bright again. 3 comments.
