60 Hz RF

it

I'm surprised you computer doesn't crash.

Not a new fangled flat screen then!!

Take a 220 volt pigtail, and hook it up to a 60 Hz resonant antenna. If necessary, use a matching network. That should do it.

A permanent magnet is analogous to a superconducting coil. But how to build a 60Hz AC permanent magnet? Simple.

Two permanent magnet rods held side by side, with alike poles adjacent, will create an extensive magnetic field in the surrounding volume. But the same two PM rods, if held side by side with unlike poles adjacent, will create no extensive magnetic field, since the adjacent opposite poles cancel out (and the field strength at a distance is ~0)

So, in order to create a "60Hz permanent magnet," spin two PM magnets so they flip end over end. Let them spin in opposite directions. Use maglev to suspend them. Spin them in a vacuum chamber. Friction will be very low, so you can keep them going at 3600RPM by using a small 'kicker' coil. Better use ceramic magnets to avoid inductive braking. Perhaps use magnetized ferrite spheres rather than rods.

Next, create a quarter-wave radiator. Build more of the levitated- bar-magnet devices. And more. Build a vast array which covers thousands of square miles of landscape. If the phases of the flipping ceramic magnets are adjusted, you can have strong N/S poles appearing and vanishing at 60Hz along the border of the array. Or let those poles rotate around the array if you prefer (and radiate circ polarized 60Hz RF.) The output will rival that of a gigantic superconducting loop antenna.

And once the array grows large enough, radiation resistance will start slowing the magnets. You'll have to add more microwatts to each kicker coil.

With even a small version of this device, probably we could use it as the stator of an induction motor, with a large number of spinning squirrel-cage rotors nearby, each running a bit below 3600RPM.

Such a rotor would benefit from having long "antennas" to couple the rotor to the ambient 60Hz b-field, "antennas" in the form of long rods composed of laminated iron sheets, or perhaps clusters of iron cable.

Antennas for picking up Mag-tricity waves!

Wait a minute. Maglev on a pair of spinning bar magnets? Wouldn't they cancel each other out?

Thanks, Rich

Is it April First already?
