We know of one exception to the conservation of energy, which

principle is conservation of mass/energy. However, mass conversion
is very much out of the ordinary, and is highly unlikely in a "magnet motor."
I believe that is incorrect. According to the physics textbooks I
have read, all sources of energy, and all forms of energy, always
reduce mass. All endothermic reactions increase mass.
Offhand, I think this is true. I was speaking of significant mass
conversion. Like, measurable. "Energy" as Jed has used it means
"releasted, removed energy."
I recall this is essential to general relativity. At least, to the
parts that everyone agrees on.
According to Philip Morrison the mass deficit has never been
confirmed in reactions on earth. Either the change in mass is far
too small to measure (for example, with a combustion or nuclear
power reactor), or the energy release is too large and too fast (for
example, with a megaton nuclear bomb).
That could be a little misleading. Mass deficit is confirmed in
nuclear reactions. Mass deficit exists, in theory, in chemical
reactions, but is far too small to be measured.
