Didn't know you were talking about free-energy videos. Anyway, those are a complete hoax. Sorry, but there's no way to create free energy. As for your son, here's a list of electronics and magnetism science kits I would recommend:

I highly recommend this one, I had one as a kid and loved it!:

$34.99 Elenco 130-in-1 Electronic Playground and Learning Center (ages 12+)

$26.49 Thames & Kosmos Magnetic Science (ages 8+)

$24.00 Thames & Kosmos Motors and Generators (ages 8+)

$18.85 4M Magnet Science Kit (ages 8+)

And here's some nice assortments of fun magnets to play with:

$19.95 46 small-medium magnets

$34.95 100 small-medium magnets

$69.95 26 medium-large magnets

Thanks! I'm a home user, and yes I meant 200kg force (Ebay sells them for about £40).

> Ok so to answer your question: you could wrap it in a rubber mold (which you can paint on in layers)

Any high rated product from Amazon.co.uk you can recommend? How about something like this: http://www.amazon.co.uk/Plastidip-Plastic-Rubber-Paint-400ml/dp/B0006SU3QW

Also maybe this? http://www.amazon.co.uk/250mls-Liquid-Latex-Mold-Special/dp/B004FPMN4C

I think the idea with this second one is to dip objects in multiple times (waiting minutes or hours between each layer), and each time a layer is added. You can dip multiple times, and get it as thick as you want.

> or even glue on sheets of rubber (probably your best bet)

Again, any product page you can point me to? Hopefully, UHU all purpose glue will stick it together. This approach will look less 'clean' than the previous though...

I don't mind not using rubber by the way.

> Remember, the thicker your protective layer, the bigger your air gap, and the weaker the strength will be.

If the distance is more than a few centimetres, the force will be the same AFAIK. It's only weaker in the sense that the metal can't physically touch the actual magnet if it's got a coating.

> And as always, be careful with magnets that strong!

That's why I want to get it coated :)

How do you rate the safety of a cube versus a cylinder versus a sphere? A sphere has no sharp edges or corners, but perhaps more importantly, flat metallic objects won't have so much surface area to 'touch' the spherical surface completely (unless the object was also curved like the magnet, which is unlikely).

Not sure how easy it is to detach metal objects from a 2" diameter sphere though compared to an equivalently strong cube (about 1.6" cube).

Any stories to share? Have you ever come close to an accident?

Neodymium magnets should be able to do what you’re asking, 5 lbs should be fine and the cost varies but you should be able to buy a larger one on amazon. Even smaller ones can have hundreds of pounds of holding power.

For example: Fishing Magnet, 400LBS 2.5 Inches Neodymium Rare Earth Magnet with Lifting Eye-Bolt Ideal for Retrieving Items in Lake,Beach,Lawn and New House(Silvery White, Pack of 1) https://www.amazon.com/dp/B07RFRH2MV/ref=cm_sw_r_cp_api_i_WMDTDbGRS47TA

You need to be careful with them though, don’t get your finger caught between two of them. They are dangerously powerful.

I'd toss some self adhesive vinyl on it and call it a day. When it gets damaged you can replace it or change colors.
