Is magnetic force a matter?

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

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)
