His measurements suggest that muons also differ from electrons in a property called magnetic moment, which governs a particle's interaction with magnetic fields.

These are superpositions of ones and zeros and are represented by, for example, the direction of spin (with respect to a magnetic field) of a particle such as an electron.

The energy released in fusion is carried mostly by neutrons, a type of subatomic particle that has no electric charge and hence cannot be confined by the magnetic bottle.
