Does A Mangetic Field Have Frequency?

  1. Jan 6, 2009 #1
    New Member - I have to say - This site is amazing- Great find, Been reading for hours now and I have come to a question I could not search'n find!

    Does a magnetic field (non-electrically generated) have a frequency?

    i.e. Earth Magnet

    Any info on this topic would be oh so interesting to me.

    As I understand, the magnetic properties of an Earth Magnet are caused by Ferromagnetism.
    This effect is due to quantum mechanical spin, not classical motion.
    So, there's no classical frequency to a magnet.

    Have you read: http://en.wikipedia.org/wiki/Magnetic_field

    there's a LOT there to digest! and note the "SEE ALSO" at the bottom of that reference.

    A stationary magnetic produces a stationary magnetic field to a stationary observer analogous to a stationary mass producing a stationary gravitational field; oscillate either and the fields follow suite.
    However an oscillating magnetic field tranforms to an electric field. And an oscillating observer will see an oscillating field.
