Forgive me, but I am finding this statement hard to accept. Thanks to the proton there will be an E field, axially symmetric and forward pointing, with a radially outward component. There will also be a B field, axially symmetric and pointing along the circumference. I don't see how either of these fields will induce a current in the wire.If a proton passes through a loop of wire, it induces a tiny current in the wire.
Northprairieman said:Thanks for the responses. So what if you had a stream of protons? Would that be equivalent to the pole of a magnet?
In this stream of protons, will each successive proton be slowed down because the proton before it passing through the loop made the loop of wire no longer uniformly neutral?

In the little diagram there, it shows a B field generated by a moving charge. So if I understand this correctly, that's a "static" B-field (not a moving B-field) and hence does not produce a magnetic flux?
Current induction refers to the process of creating an electric current in a conducting loop by changing the magnetic flux through the loop. This process can result in energy loss due to the creation of an opposing current, known as an induced current, which generates heat and dissipates energy.
Energy loss occurs when current is induced in a loop because of the principle of electromagnetic induction. When a changing magnetic field passes through a conducting loop, it induces an opposing current in the loop, which creates a resistance to the flow of the original current and results in energy loss.
The amount of energy lost during current induction can be affected by various factors, such as the strength of the magnetic field, the size and shape of the conducting loop, and the speed at which the magnetic field is changing. The greater these factors are, the more energy will be lost.
Energy loss during current induction can be minimized by using materials with low electrical resistance, such as superconductors, which have virtually zero resistance. Additionally, using a smaller and more efficient conducting loop can also reduce energy loss.
No, energy loss during current induction is not always a negative thing. In some cases, it can be intentionally harnessed for useful purposes, such as in transformers, which use current induction to transfer energy from one circuit to another. However, in most cases, energy loss is considered undesirable and steps are taken to minimize it.
