What is a temporary magnet caused by an electrical current?
A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.
How can a magnet produce electricity when spun very fast?
When a magnet is spun very fast within a coil of wire, it creates a changing magnetic field. This changing magnetic field induces an electric current in the wire, following Faraday's law of electromagnetic induction. The induced current is the source of electricity generated by the spinning magnet.
What are moving charges?
It means that they are charges (that usually refers to electrical charges), and that they don't move (or don't move significantly).
In synchronous motor theory is excitation current the same as field current?
Yes, in synchronous motor theory, excitation current is the same as field current. This current is used to produce the magnetic field in the rotor that interacts with the stator current to generate torque and make the motor operate synchronously.
What did Wegener called his theory of moving continents?
Alfred Wegener called his theory of moving continents "continental drift." He proposed that Earth's continents were once joined together in a single supercontinent called Pangea, which later broke apart and drifted to their current positions.
What does magnetic do?
There are two theories that are used to explain magnetic therapy. One theory maintains that magnets produce a slight electrical current.

Why does passing a current through a wire create a magnet?
That is, basically, the way ALL magnets are created - by moving electric charges. In the case of a permanent magnet, it is mainly the electrons orbiting their atoms that produce this effect. As to the "why", the Special Theory of Relativity provides an answer, but it is fairly complicated. The summary paragraph on Wikipedia (article "Magnetism") says: "As a consequence of Einstein's theory of special relativity, electricity and magnetism are fundamentally interlinked. Both magnetism lacking electricity, and electricity without magnetism, are inconsistent with special relativity, due to such effects as length contraction, time dilation, and the fact that the magnetic force is velocity-dependent. However, when both electricity and magnetism are taken into account, the resulting theory (electromagnetism) is fully consistent with special relativity. ..." The Wikipedia article "Classical electromagnetism and special relativity" provides a more detailed explanation about the relationship between electricity and magnetism, according to the Special Theory of Relativity - but the math is a bit too complicated for my liking.

What makes a magnet a magnet?
The arrangement of molecules in a magnet makes itself a magnet.if u want to know further,try searching "Ewing's molecular theory of magnetism".
Do science students produce a theory or a hypothesis?
They produce a hypothesis. A theory requires extensive support.
What is the current ring theory of magnetism?
The current ring theory of magnetism suggests that magnetic materials possess microscopic "current loops" created by the movement of electrons within the material. These current loops produce magnetic fields and are responsible for the magnetic properties observed in materials.
