Electricity on the Move: 17

Electricity can flow through solid matter, sometimes with great difficulty, sometimes with ease and very occasionally with no effort  at all. As it flows, electricity generates a magnetic field which can influence other currents of electricity at a distance.

What causes electricity to move from one place to another? What causes electrical resistance and what use can we put it to?           What causes the magnetic field and what uses can we put it to?

This show uses numerous demonstrations to follow the flow of electrical current, from its source in the discovery of the voltaic cell, via the landmarks of Michael Faraday to the exciting future of room temperature superconductivity.

Along the way we take the chance to make sparks and explosions which help anyone to see that electricity is a vital, exciting part of the modern world.
