Wide-Bore Low-Frequency Magnetic Spinner for Non-Contact E-Field Generation in a Tissue via Faraday's Law of Induction

Wide-bore mechanical rotating magnetic spinner with ~1,300 Alnico permanent magnets. The rotating magnetic field is perpendicular to the ring axis. Measured magnetic field at the bore center is 32 mT.  User controlled rotation speed of 0-15 Hz.

To create alternating electric field/electric current in biological tissues (bones) via Faraday's law of induction. A test movie is available at the Dropbox link
