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...

I'm not going to use the Earth's North and South poles to magnetize my circular magnet, but instead, a very powerful solenoid wrapped around it. Jun 16, 2016 #85 Charles Link Homework Helper Insights Author Gold Member 5,847 3,075 Part Toon said: I don't think you quite ...
completely and attach both ends of the wire to a battery. Once the circuit is closed, the metal (and the wires around it) will create a magnet and whatever magnet is nearby will be attracted or repelled by it. This is a much more complicated, but more permanent way to magnetize metal...
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...
By the 12th century, people had discovered that they could use lodestone to magnetize pieces of iron, creating a compass. Repeatedly rubbing lodestone along an iron needle in one direction magnetized the needle. It would then align itself in a north-south direction when suspended. Eventually, sci...
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 ...
Magnetize It You can buy magnets to mount your poster on the wall. Buy round or square magnets online or at your local hardware store. Use double-sided tape to stick one magnet to the wall that corresponds with each corner of your poster. Place the poster on the wall and put the second...
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...
