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 electrical resistance and what use can we put it to?
What causes the magnetic field and what uses can we put it to?
The 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 and Kammerlingh Onnes to the exciting future of room temperature superconductivity.
