Dr Andrew Steele explains how a superconducting magnetic levitation or maglev train works. [5 minutes]
An ongoing project on superconductivity produced to celebrate the centenary of the discovery of superconductivity in 2011. It consists of a series of video lectures by leading world experts in academia and...
A: Demonstrates the power of Gauss’s Law both in the way it can be used to help to calculate the electric field near some arrangements of charge and to understand what is going on in some practical...
1: carbon dioxide and other gases in the atmosphere. Describeds some of the features of current models including uncertanties introduced by could and ocean absorption. 2: introduces nuclear radiation and...
The second of three working videos course S343. [See synopses of individual programmes for details of content.]
Shows an inorganic chemical research laboratory at the University of Edinburgh and the applications laboratory of an NMR instrument maker, Bruker Spectrospin, in West Germany. In Edinburgh Professor E A V...
Outlines the research work in the University of Liverpool Department of Electrical Engineering and Electronics on the new magnetic material meodymium-iron-boron. This is part of an EEC funded concerted...
Explores the electromagnetic force. In six 10-minute segments: Earth’s Magnetic Field (discovery of lodestone, magnetic declination and the angle of inclination); Magnetism and Electron Flow; Domain Theory...
Starts with a series of demonstrations showing the three electromagnetic principles on which the induction motor is based. Then uses models to explain how a linear induction motor works. The new magnetic...
The Meissner effect is shown by levitation of a small permanent magnet over a super-conducting dish. It is demonstrated that a magnet will levitate over a sufficiently thick dish but not over a very thin...
