E=mc2 and electric charge

  1. Aug 20, 2014 #1
    If m mass is complete ly distroy by e=mc2......then what happen about electric charge and magnetic energy?

    Electric charge is conserved, so the only reactions that convert massive charged particles completely into energy have to start with zero net charge. For example, an electron (charge -1) and a positron (charge +1) can combine and convert completely to energy.

    Be aware that are a whole bunch of thngs other than charge that have to be consered as well.

    Thee's no such thing as "magnetic energy".

    Okey .is this possible, mass and charge can live separate ly?

    Mass and charge are both properties of objects. There are uncharged particles with mass, such as a neutron and a neutrino.

    Newton make of quarks which have charge

    True, neutrons are made of charged quarks. However, neutrinos are not.

    You can also have types of charge without mass, just not the electric charge. Gluons have color charge, and are mass less.
