An electric current produces a magnetic field.
That's called an electromagnet.
The electric current.
An electromagnet is temporary because the field disappears when the current is switched off.
That's a permanent magnet. After all, the compass doesn't need an electrical current, right?That's a permanent magnet.

Electromagnet. Magnetic only when current is flowing in the coil.

A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.
By making the magnetic field around it a negative charge

An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
I assume you mean in a setup similar to an electrical generator. Here, current is ONLY produced if there is relative movement, between the magnet and coil. Without movement, there will be no current.
If it has been magnetized by another magnet, then it is just a temporary magnet, but if it uses an electric current, then it is an electro-magnet.
Electrical
Faraday found that a wire passed by a magnet induces a current in the wire. This led to making an electrical generator.
