http://en.wikipedia.org/wiki/Proton_magnetometer I guess I confused NMR with the frequency of a magnetic field. Thanks for helping clear that up for me. I'm still not clear on what is actually causing the magnetic attraction between two magnets. From what I have read (and I am probably...

So that I am clear, the magnetic field of a permanent magnet are not caused by an energy wave, because it does not have a frequency. So what is causing the magnetic field? If it isn't a particle and isn't an energy wave, what is the force that is causing the attraction or repulsion between two...

Also, when they say that the Earth's magnetic field has a frequency of between 900 hz and 4.3 khz, what are the measuring? Sorry if these questions seem very basic, I am a scientist (PhD in biochemistry and molecular biology), but I am not familiar with physics other than what I learned in...

Also, with respect to your comment of how frequencies are a measure of something regularly changing in time, when you turn on a light bulb, what is the time that is measured? Is it the time that the photons take to oscillate through space as it propagates from the source?

Thanks for the information. So if it is not a part of the EM spectrum, what is being measured when you measure the intensity? Is there a magneton, something like the equivalent of a photon?

Hello all, I am a newbie here but have a question that I was hoping someone could answer. Would a permanent magnet give off a single frequency or would it give off a spectrum of frequencies, like an incadescent light bulb can give off a spectrum of frequencies? I can measure the intensity...
