(a) Positive charges move in the direction of the electric field and the same direction as conventional current. (b) Negative charges move in the direction opposite to the electric field.

The equation for the force on the wire is given as F=BIL, where B is the strength of the magnetic field, I is the current in amps and L is the length of the wire in and perpendicular to the field.

A measure of this limit on charge flow is called resistance. The simplest combinations of resistors are the series and parallel connections . The total resistance of a combination of resistors depends on both their individual values and how they are connected.

It is the change in magnetic field that creates the current in the following way: a changing magnetic field induces an electric field, which results in the induced voltage. The faster the motion, the greater the voltage, and there is no voltage when the magnet is stationary relative to the coil.
