I merged this to electrodynamic levitation. It's known from the work of Professor Laithwaite that this is just the same scheme as virtually any other type of electrodynamic magnetic levitation scheme.
And it's not levitation due to radiation, since the coil isn't arranged as a transmitter aerial, even though it's driven by a radio frequency, it's just an electromagnet. Electromagnets aren't aerials, aerials have to have a specific impedance and are driven at resonance, but this isn't. And it absolutely doesn't work at a distance, it's strictly a near field phenomena, like any other magnetic levitation scheme. If it was radiation then it would work at a distance. It relies on the interaction between the magnetic field generated in the levitated object interacting with the magnetic field in the electromagnet. Magnetic fields like that are near field. The term 'electomagnetic' in the title refers to 'electromagnets' NOT electromagnetic radiation.- Sheer Incompetence ( talk) Now with added dubiosity! 17:09, 1 November 2011 (UTC)
