Friday January 18th: WITHOUT VISIBLE MEANS OF SUPPORT A Demonstration of MAGNETIC LEVITATION

DSC01303Magnetic fields are an invisible force, which performs its magic even in a complete vacuum. We demonstrate five different kinds of magnetic levitation.

See with your own eyes the wonders of pyrolytic graphite, a newfangled “diamagnetic” material!

Why copper and aluminum, normally nonmagnetic metals, are strongly repelled by ac magnetic fields.

Learn how MAGLEV trains work.

The dreaded “Earnshaw’s Theorem” states that stable magnetic levitation is impossible. But witness how a simple, homemade, electronic circuit can evade Earnshaw’s theorem and stabilize the levitation of a small steel ball.

Free and open to the public! The doors open at 7pm, the talk starts at 7:30.
We’re located at 1936 5th Avenue, in the garage around back on Watson.
Look for our flag above the door.

    I presume the guests need to bring their own frogs?
