Why do magnets attract?
Magnets are made up of atoms such as iron, cobalt and nickel. Their atoms have special internal structures and have their own magnetic moments. Magnets can generate magnetic fields and attract ferromagnetic substances, such as iron, nickel, cobalt and other metals.
Magnets can be divided into "permanent magnets" and "non-permanent magnets". Permanent magnets can be natural products, also known as natural magnets, or artificial. Non-permanent magnets, such as electromagnets, are magnetic only under certain conditions.

Magnetic field:
A magnetic field is a substance that produces a magnetic effect on a magnet placed in it, which is called a magnetic field. The basic characteristic of magnetic field is that it can exert a force on the moving charge, that is, the charged conductor is acted by the magnetic field in the magnetic field.
This is the strength or distance of magnetic field, the source of current and magnet. Modern theory shows that magnetic force is the relativistic effect of electric field force, and the area affected by magnetic force shows that the charge passing through this area or the magnetic pole placed in this area will be affected by mechanical force.
