Would this create an electromagnetic wave?

I know that a changing magnetic field creates a changing electric field, which creates a changing magnetic field, which in turn creates a changing electric field. My question is, if one were to shake a magnet really hard would this create an electromagnetic wave? Possibly a radio wave. I say a radio wave because obviously no one sees or feels anything when one shakes a magnet.

If you could shake the magnet very fast (>100kHz), it would produce a radio wave.

I think, technically, the radio wave spectrum approaches 0Hz. So even your 5Hz wave would be radio. Just very, very long waves... ~20,000km wavelength.
