Why change the thickness of copper wire can not change the current size of electromagnetic induction?
Electromagnetic induction (Electromagnetic induction) refers to the phenomenon of conductor changes in magnetic flux, will produce electromotive force. The electromotive force is called electromotive force or electromotive force, if the conductor into a closed loop, the electromotive force will drive the flow of electrons, the formation of induction current, that is to say this the current and the induced electromotive force and resistance of bribery
In fact, the current still varies because the wire thickness changes the resistance of the wire, but this change is very small (below 1 ohms), so it is difficult to detect this change when we test the current
The induced electromotive force with epsilon said that epsilon = n / delta phi delta T this is Faraday's law of electromagnetic induction, this formula shows the change speed of induction voltage and magnetic flux and the number of turns of the coil, and a wire coil is independent of the thickness, so change the wire thickness, current does not change
