This bottle is hypnotizing. You will not be able to put it down. It’s as if your hands are now magnetized too and must procrastinate all work and housekeeping in order to see how the magical ink shards move around. We had to make three of these so that all of us had one to play...
The easiest way to create a powerful magnetic field is by creating a powerful electromagnet. Electromagnets are used for everything from powering tiny electronic switches (called relays) to lifting huge pieces of scrap metal. The density of the winding, the amount of current flowing through the m...

which made the needle behave like a magnet. You had to rub in one direction to get the atoms to all line up in the same manner. If you had rubbed back and forth, the atoms would not have lined up as well, and the magnetic field would probably not be as strong, if one was create...
To make a magnet repel a metal, one must first understand the properties of a magnet. A magnet has two poles, a north pole and a south pole. When magnets are placed near each other, opposite poles attract and like poles repel one another. When a metal enters a magnetic field, all of...

Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet...
