It is common knowledge that radio-wave energy is created by oscillating electric currents in conductors. These are electro-magnetic fields. Now, on the subject of purely magnetic fields, is it possible to generate a magnetic field wave in a similar manner.? This would be a magnetic wave which propagates outward from its source in the same manner as an Em wave. Natrurally (I surmise) this wave would be polarised in a manner like a magnetic field surrounding a magnet. As far as I know this has not been done and probably never will be done due to the intrinsic nature of magnetic fields. Please give me your best answer. :0)
Thats what an electromagnetic field IS---a vibrating magnetic field. You just cant have a magnetic field by itself---as it is the wake resulting from a movement of electrons--And vice versa---move a magnetic field and you move electrons too---they are different sides of the same thing. electrons are moving even in a permanent magnet---in circles around the iron nucleus.--It is just that in such magnets the atoms are lined up---and the force from each electron joins with the other. In all other materials, the electrons are all aligned different and cancel out each other---so they do not appear to have detectable magnetic effects. So magnetism comes from a moving electron---- or moving a magnetic field will move electrons---they are different aspects of the same thing from different angles. Neither are seperate items---Thats why they are called an electromagnetic field.
