Although the name of a magnet is only 'magnetic', it also has an 'electric' aspect. From a microscopic perspective, magnetism is the embodiment of electricity, so there must be an electric phenomenon if there is a magnetic phenomenon.

Magnets are transmitted by a field, which is a massless substance called virtual particles. A magnetic field is composed of virtual photons. But sometimes virtual photons also have mass, such as the relativistic mass generated by motion.

In fact, there is no clear boundary between virtual photons and photons, and sometimes the two are equivalent. It can be understood that magnetic fields transmit interactions through virtual photons that cannot be described by physical particles.
