... field. If it does move it feels a maximum force when it is moving in a direction perpendicular to the magnetic field lines and zero force when it is moving parallel to the field. For a beam of electrons (current) perpendicular to a magnetic field, point the index finger of your left hand in the dire ...

... First of all, if the kinetic energies are the same, then when brought to rest, the non conservative work done on each would have to be the same based on work-energy principle. Also, since both have the same kinetic energies we have ½ m1v12 = ½ m2v22 … since the velocity is squared an increase in mas ...

... It seems that microscopic electric currents are the ultimate cause of magnetism. For example, each neutron has a little bit of internal magnetism; in technical language, we say that each neutron has a non-zero magnetic dipole moment. In other words, part of the nature of a neutron is that it acts l ...
