Magnetism without charge

  1. Sep 19, 2011 #1
    In order for magnetism to be present doesn't electricity have to be present? A electron moves from a negative charge to positive charge and magnetism is the motion of electric charge, resulting in attractive and repulsive forces between objects. It seems to me that if a negative and positve charge exist then magnetism must present. Any insight would be greatly appreciated because we are starting electrical charges and forces in my physics II class and would like someone elses insight, please.

    When there is Electricity (MOVEMENT of charges) then there is Magnetism i.e moving electrons (Current) Produce magnetic field around them.

    Secondly Changing Magnetic field causes Electricity to flow in wires put in changing magnetic field.[ Faraday's Law ]

    So Electricity and Magnetism Comes in pair.

    It depends on how far you want to go with this. Note that both neutrons and neutrinos are neutral, and yet, they have a net magnetic moment due to the spin angular quantum number.

    On neutrino magnetic moment...

    I was under the impression that experiments so far have not definitively measured a neutrino magnetic moment, but only established upper limits.

    Perhaps you know of more recent results? If so, could you give references please?

    Thank you for this explanation because I think I am starting to grasp the concept of electrons, they seem to be the ones doing the traveling which creates the work/potential. Electrons are in everything and are constantly moving and therefore creating some sort of electricity....??
