Magnetic Force Exerted by a Magnetic Field on a Single
... If the magnetic field is perpendicular to the velocity of the electrons, the force exerted on the electrons is perpendicular to both the magnetic field and the velocity. c. Your friend says that the beam of electrons is deflected by the magnet because the electrons are charged particles and the magn ...
