    Magnetic field on rotating electron.

    new problem a straight current carrying wire form a loop along its way. what is the magnetic field at the loops centre? if the loop is rotated 90° about AB axis what will be the new magnetic field? (sorry for the clumsy pic arrow shows direction of current. )...

    Magnetic field on rotating electron.

    Homework Statement an electron is rotating around a proton with a velocity of 2*10^6 m/s on circular path of diameter 5*10^-11 m. what is the magnetic field (B) ? the centripetal force on the electron and the magnetic force should be equal and mv^2/r = Bqv or B= mv/qr.Homework Equations...
