Is magnetic force a matter?

I will mark the one who gives the best explination brainliest.

the electric and magnetic fields which surround a charged object like an electron do store energy, and therefore have a rest mass

Normally we wouldn't call any of these fields "matter", but it is true that the electric and magnetic fields which surround a charged object like an electron do store energy, and therefore have a rest mass, via E=mc^2 (in a reference frame in which the electron has no momentum)
