... • When the magnet is moved close to the coil, the magnetic field lines come into contact with the electrons in the coil. • This creates a potential difference. This potential difference causes the electrons to move (what we call current) • The coil now has its own magnetic field which opposes the ap ...

... Back EMF is an electromagnetic force that opposes the main current flow in a circuit. When the coil of a motor rotates, it is cutting magnetic flux, which will induce an EMF that opposes the cause of induction. Thus, the induced current will flow in the opposite direction of the input current that l ...

... A square coil of wire with side 5.0 cm contains 100 loops and is perpendicular to a uniform 0.60 T magnetic field. It is quickly and uniformly pulled from the field to a region where B drops to zero. At t=0, the right edge of the coil is at the edge of the field. It takes 0.100 s to move the whole ...
