You cannot have a magnetic field without having an electric field, but you can have an electric field without having a magnetic field.
Dominic Rogers
Each pole of a magnetic field has a north pole and a south pole; the south pole points to geographic north while the north pole points towards geographic south.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off.
Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves.
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.[10][16] In particular, a phenomenon that appears purely electric or purely magnetic to one observer may be a mix of both to another, or more generally the relative contributions of electricity and magnetism are dependent on the frame of reference. Thus, special relativity "mixes" electricity and magnetism into a single, inseparable phenomenon called electromagnetism, analogous to how relativity "mixes" space and time into spacetime.

Magnetism is, in a sense, an "illusion".
I don't mean it's not something which can push or pull.
But it's a relativistic effect of moving charges.

There are no magnetic "particles". Quantum theory says magnetic monopoles COULD exist, but none have ever been found.

Basically this.

every electron has a tiny magnetic moment due to its spin. for the most part, what we normally regard as magnetism arises as either electromagnets or ferromagnets.
electromagnets use current in a coil to organize the magnetic moments of the electrons.
in ferromagnets, the material has unpaired electrons whose spins can also spontaneously align (paired electrons have opposite spins and cancel out the magnetic moment).

Monopoles are theoretically possible
Jayden Williams
when an element has a last one spin in its last orbital, then it is paramagnetic.
