Induction, magnetism and conductivity‏

Click For Summary
Relative motion between a permanent magnet and a conductor induces electric current in the wire, with the induced current depending on the type of conductor used. The induced electromotive force (emf) is determined by the rate of change of the magnetic field and is not influenced by the conductor's material, while the current produced does depend on the conductor's properties, such as conductivity and magnetic characteristics. Iron, having higher permeability than copper, may produce greater induced current due to its magnetic properties, but this effect is also influenced by the physical dimensions of the wire and the loop area. The discussion highlights the complexity of factors affecting induced current, including material conductivity, magnetic susceptibility, and circuit configuration. Ultimately, the relationship between magnetic properties and conductivity is intricate, requiring experimental validation for specific scenarios.

Don't you have a voltmeter, piece of wire and a magnet? Try it out and you will see. How else do you expect anyone shall convince you? I already gave you two links that confirm current can indeed be induced in a straight wire. You think people around the world just hallucinated that and came up with the same equation?
Faraday's law is a fundamental part of electromagnetic theory. If you think I am failing to appreciate that, you are mistaken. You do not seem to be able to read or to understand what I have written.
