A permanent magnet is simply a ferromagnetic material in which a majority of the
magnetic domains are aligned with each other to produce a net magnetic dipole
moment.
Electromagnetic is an interaction between electricity and magnetism, as when an
electric current or a changing electric field generates a magnetic field, or when a
changing magnetic field generates an electric field.

The magnetic field around a straight wire is not strong.
A strong field can be made by coiling the wire around a piece of soft iron.
