The basic idea is to make a magnet float by holding it up withthe repelling force from another magnet. Magnets can repel each other with enough force. Having enough force to levitate it isn't the problem. ... The floating magnet tends to rotate around, flipping itself to attract to the ...

From the compass to electricity, the accidental discovery of magnetic rock altered the course of humanity way beyond decorative refrigerator magnets.
The chair and the base incorporate magnets of opposing poles to push the chair upwards. Some people believe magnets have health benefits, like weight loss and muscle contouring, which gives this chair added value. But beware. The chair comes with some standard warnings: Keep it away from ...
as shown in the diagram at the right. If you think of the world this way, then you can see that the normal "opposites attract" rule of magnets would cause the north end of the compass needle to point toward the south end of the buried bar magnet. So the compass points toward the No...

magnetic particles. The liquid dispersion medium is designed so that the particles can be pulled through the liquid in response to magnetic force applied by the pen or eraser, but they will not change their position (float or sink) due togravity. To do this, the liquid has special ...
Here are some ideas for activities involving your liquid magnet ferrofluid: Use a strong magnet to float a penny on top of the ferrofluid. Use magnets to drag the ferrofluid up the sides of a container. Bring a magnet close to the ferrofluid to see spikes form, following the lines of the...
