... Now the force, Fq, on each little charge, q, is equal to the total force on the wire (F = IlB) divided by the number of charges over which this force is spread, that is, nl, the number per metre times the length. So Fq = IlB/nl = IB/n. We have just seen that, in terms of moving charges, the current, ...

... Draw the direction of S in a sketch, make sure that the direction is unambiguous from your drawing. If necessary also describe in words. e. Is the total power flux going into the inductor or getting out of the inductor? Use two methods to determine the direction of the power: (1) consider the change ...
