PERSISTENT SUPERCONDUCTING MAGNET VICTORY!!!

21 10 2010

All photos.

I have put the superconducting magnet into a persistent state!!!!!

Power supplies off, magnet still going!

Details to follow.

UPDATE:

OK. Here it is. The units are in raw volts coming from the magnetometer and the current sensing resistor (0.008 ohms). The red is the current going into the superconducting coil, the white is the magnetic field. You can see that the current drops off, but the magnetic field persists. WIN!!!!

The magnetic field gradually falls off over the course of an hour.

This is the setup:

SC coil in the dewar:

Here is the schematic:

It was all controlled manually by switching the power supplies on and off.

Wow … congratulations ….

A current running through a closed loop producing a persistent magnetic field… sound strange and kinda awesome at the same time.

I need one of those! I wanna build one too!

From the description on Talk-Polywell.org, that’s what I thought you must have built. This would make a nice demo kit for people bored with levitating rare earth magnets over a disk of HTSC.

Awesome job Mark,
Thought you may find this interesting even though you have it working..may extend persistence?
