... 2-nd generation HTS (2G) wires has allowed the production of the first long length 2G-wire YBCO coil this year [1]. Thus, problems of HTS coil design and optimization have become relevant. The critical current and averaged E-I curve of the HTS coil are insufficient parameteres of its design. Further ...

In Figure 5.4, you can see a bar magnet which is hanging from a fine thread. When it is left for a while, one end always points north. This end of the magnet is called the north-se ...

Quantifying Electric and Magnetic Field Coupling
... Figure 1 illustrates electric field coupling in a simple TEMcell test set-up. A voltage difference between a small patch of metal and the wall of the TEM cell produces lines of electric flux that emanate from the patch. Most of these flux lines terminate on the wall of the TEM cell; however a small ...

Faraday paradox
This article describes the Faraday paradox in electromagnetism. There are many Faraday paradoxs in electrochemistry: see Faraday paradox (electrochemistry).The Faraday paradox (or Faraday's paradox) is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes:1. Faraday's law predicts that there will be zero EMF but there is a non-zero EMF.2. Faraday's law predicts that there will be a non-zero EMF but there is a zero EMF.Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
