... (b) By integrating the dot product of the Maxwell stress tensor with the area element d~a over the xy plane, determine the force of one charge on the other. (This force is much easier to obtain by a more ordinary method, of course, but you aren’t allowed to use that easier method here, except as a c ...

The first lesson - Lets Upgrade Your Knowledge
... You can make a electric generator to see how the three factors which weaken or strengthen a electromagnet actually effect the power of the electromagnet. At the end of the experiment the experiment should be successful and you can see how the main factor which changes the power is the strength of th ...

... Pressure is the amount of force pushing on a certain area. For a certain area, the bigger the force, the bigger the pressure. For a certain force, the bigger the area, the smaller the pressure. In this picture, the thumb is putting a force onto the head of the pin. The force is transferred to the po ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
