Actually brainwaves are more electrical in nature that magnetic.
Magnetic fields are usually caused by an electrical current passing
through a conductor. Your brainwaves are not pure audio however if by
that you mean pure sine wave tones. Brainwaves are extremely complex
waveforms made up of a wide range of frequencies. Entrainment refers
to a single frequency becoming dominant, or louder than the others and
affecting the mental state in some way. This can be seen most easily
in an EEG that takes a feed and filters it into several channels that
can only pass a narrow band of frequencies or through doing a Fast
Fourier Transform (FFT) on the wave that shows the different
frequencies as peaks.

The brain will tend to entrain on any rhythmic stimulus regardless of
the sense affected. But I'm not sure that listening to a source
designed to power a magnetic transducer would work very well. The
clicks are likely the leading and trailing edges of the DC current
that urns the transducer on and off, much like the on and off pulses
to a set of audiostrobe goggles.

Hope this helps.
