13.3: Lenz''s Law

Alternatively, we can determine the direction of the induced current by treating the current loop as an electromagnet that opposes the approach of the north pole of the bar magnet. This occurs when the induced current flows as shown, for then the face of the loop nearer the approaching magnet is also a north pole.

ESSENTIAL GUIDE TO BRUSHED MOTOR …

Changing the direction of rotation of the motor shaft is generally achieved by simply reversing the current direction in the motor coils. One superior method of reversing the current in a motor is to use an H-bridge. This is a bridge circuit made with semiconductor (MOSFET) switches arranged in an H configuration (Fig. 3).

Current flow in batteries?

The easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for current to return to its source, there will be no current flow.
