Rubbing the magnet against the needle in one direction caused the iron atoms in the object to line up and create a weak magnetic field, 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...
In a strong magnetic field, some walls disappear entirely. The resulting magnet's strength depends on the amount of force used to move the domains. Its permanence, or retentivity, depends on how difficult it was to encourage the domains to align. Materials that are hard to magnetize generally...
There is a horizontal tube -- the same one the patient enters -- running through the magnet from front to back. This tube is known as the bore. But this isn't just any magnet -- we're dealing with an incredibly strong system here, one capable of producing a large, stable magnetic ...

In a typical reed switch, the two contacts (which look like metal reeds) are made from a ferromagnetic material (that means something as easy to magnetize as iron), plated with a hardwearing metal such as rhodium or ruthenium (to give them a long life as they switch on and off), and...
You can magnetize them again by rubbing a magnet on it. Putting the 'Electro' in 'Electromagnet' Since you need an electrical current to operate an electromagnet, where does it come from? The quick answer is that anything that produces a current can power an electromagnet. From the small ...
