A voltage only occurs between two points of different electrical potential. And a current can only flow when a conductor or resistor is in between these two potentials. This also applies to a human body which gets an electric shock: The body has to get between two voltage potentials. Only then a current can flow into the body and out again.

Magnetic materials. Magnetically 'soft' materials - materials that are easy to magnetise, demagnetise and remagnetise - are widely used in electrical power systems. They play a crucial role in transformers and devices like motors and generators that convert one form of energy into another, for example, electrical power into mechanical.
