... Counter EMF Backlash! • In some devices such as electric motors and relays, the Counter EMF can cause problems. • When the device is turned off, the magnetic field collapses, inducing a strong Counter EMF. • This can be strong enough that it can cause an arc in the switch that controls the device. ...
