The magnets spinning at that speed creates a frequency which can interfere with other radio signals.
Does it tho? It's basically an electric generator
It wouldn't produce anything. For magnets to induce electricity they require a conductor and air isn't one, at least not a good enough one. Without electrical current, there's no voltage, nor constant or oscillating kind of current and therefore no radio frequencies. An electronic crystal and a handful of components could.
Electricity isn't the same as electromagnetic radiation. A varying magnetic field induces a varying electric field which radiates into space as an EM wave. See Maxwell's equations.
Please describe "as if I'm 5yo" how a radio broadcasting antenna works? Thanks! =)
