Electron motion in electric and magnetic fields
... Motion in electric and magnetic fields Magnetic fields The force (F) on a wire of length L carrying a current I in a magnetic field of strength B is given by the equation: F = BIL . But Q = It and since Q = e for an electron and v = L/t you can show that : Magnetic force on an electron = BIL = B[e/t ...
