Inverter Magnet

Hehehe - It's magnetic magic - very powerful magnets can pinch skin when being attracted - not a good idea for small fingers on kids.

The inverter magnet was only briefly entertaining without additional equipment (iron filings or something).But it works exactly as advertised, and I am happy.

Warning about brittle magnets should be bigger.

I had trouble getting my inverter magnet to work and I was very surprised and delighted to find that Hendrik Ball responded to me personally when I sent a query about my problem. He patiently zeroed in on the solution (move away from radiant floor heat pipes and then metal connecting my table leaves, etc). Thank you!

the product doesnt work a it should. I bought it to amaze my daughter but cant let her use it as it is too dangerous. It is very difficult to keep the magnets the right distance from each other, the smaller magnet jumps onto the larger one and hurts when it catches your hand. I'd like to return it actually as its a bit of a let down.

This was very disappointing. The video shows an impressive gap between the magnets, the instructions say 4 - 7 mm, with mine it was only 2 -3 mm. In one of the six stable positions it was impossible to stop the test magnet jumping onto the top of the other magnet. This product barely works and needs better quality control.

Service rating : I appreciate your speedy response to my first comment. Please see my response below.
Product rating : For this device to work there must be the correct balance of strength between the central magnet and the six peripheral magnets. In my case I suspect that the peripheral magnets are weaker than optimum. That there is a variation in strength of these magnets is demonstrated by the fact that in only one of the six stable positions would the test magnet jump. I know that these kind of magnets can be weakened by heat, for example. You say that shipped magnets are identical to the ones demonstrated. Do you test the strength of the shipped magnets? To what accuracy?

One thing that does affect the magnets is if there is any metal in the table. Initially we tried the inverter magnet on a table that had a metal frame, and there were certain positions on the table, when the magnet was above the metal frame, where it worked less well. Also the table does need to be smooth. If there is any roughness, then there is a tendency for the magnets to jump and end up in contact. The magnets we demonstrated in the video are identical to the ones we send out, so the effect should be the same.
