Would this create an electromagnetic wave?

Click For Summary
SUMMARY

Shaking a magnet rapidly can indeed generate an electromagnetic wave, specifically in the radio wave spectrum, if the frequency exceeds 100kHz. The discussion highlights the relationship between changing magnetic and electric fields, confirming that a sufficiently fast oscillation of a magnet can produce radio waves. It is noted that even very low frequencies, such as 5Hz, fall within the radio wave spectrum, resulting in extremely long wavelengths of approximately 20,000 km.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Knowledge of radio wave frequency ranges
  • Familiarity with the principles of oscillating magnetic fields
  • Basic concepts of wave propagation
NEXT STEPS
  • Research the properties of electromagnetic waves

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.
