In this instructable, I am going to show you how to build a levitating platform with the induction heater from my previous instructable.

Lenz's Law states that the direction of current induced in a conductor by a changing magnetic field due to Faraday's law of induction will be such that it will create a field that opposes the change that produced it.

The induction heater coil is producing an alternating magnetic field that induces eddy currents in the aluminum. The currents flowing through the aluminum produces an opposite magnetic field that repels the coil. A diamagnetic material like copper or pyrolytic graphite would levitate higher. Innovations in super conductors would make this technology incredibly more useful.

Step 1: What You Will Need

1. Induction Heater from my last instructable

2. Aluminum Extrusions with hardware. You can use wood or whatever else you want to build the structure.

3. Wire. I used Litz wire but you can experiment around with wire that you have on hand that is thicker than 14AWG.

4. Aluminum Foil from the grocery store

5. Aluminum armature wire. You can also use solid core coper wire without insulation

6. Fire pad to keep heat from transferring to your table.

7. Terminal Block for connecting the coil to the heater

thumbs up for the AVE ruler
<p>It's quite skookum!</p>
<p>Some would say Skookum as Frig</p>
<p>It chooches pretty good! </p>
Nice job wrangling those pixies, looks skookum as frig!
<p>Fascinating. I'm curious. Would this setup levitate fragments/crumbs/grains of aluminium -- albeit less efficiently -- or does one need a sheet of metal before it'll lift? And, if so, will the fragments clump together or lift off the ground like a cloud of particles?</p>
<p>Thanks! The more surface area, the more lift you will generate. If you fragmented the foil, you would be breaking up the current loops induced into the foil that are responsible for generating the lift. If you had a much, much more powerful field, you could lift small pieces but they would just fly off the coil as if you just blew them away. You would need a barrier to contain them. </p>
is that one of AvE's ruler things?
<p>It sure is!</p>
Nice one, voted for your instructable. Keep up the good work! :)
<p>Thank you!</p>
