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...

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...
Magnetize a piece of metal such as a paper clip, by rubbing it against a permanent magnet. The paper clip can pick up other paper clips and small metal objects. It will also behave like a small magnet. When it is attached to another object and brought near another magnet of similar stre...
When the switch is flipped to the on position, electricity can flow from the bottom terminal, through the electromagnet, up to the moving contact, across to the stationary contact, and out to the upper terminal. The electricity magnetizes the electromagnet. Increasing current boosts the ...
If I meet a person named Jacob and see him as a Blue Jay smoking a corncob pipe. But I don’t want to let the association just float around in the void. I want to Magnetize it somewhere. To do that, I put the Magnetic Imagery in a Memory Palace. ...
Reported June 9 inNeuron, the findings reveal more about how a change in an animal's internal state can push it to stop doing something it was previously motivated to do, like how a person tends to stop eating when their brain indicates their stomach is full even if appetizing food remains...
Bobbing and weaving across a stage he shared with giant costumed animals, a six-person dance ensemble, and swirling rock formations, it’s obvious the rapper has an insatiable desire to entertain and magnetize. As expected, songs like "Old Town Road" and "What I Want" proved...
Rub one end of the sewing needle across the magnet about 50 times. This will magnetize the needle. Paint the tip of the magnetized end of the needle. Use a black marker instead of paint to mark the needle. Step 4 Fill the bowl or cup with water just until the cork begins to float....
is there a way to reverse magnet to magnetize non-metals instead of metals? 2 Moses Damulira ⚠ Thanks for such educative information,My questions are: How can permanent magnetization be removed?,What role does a magnet play in a loud speaker so that we can hear and how does the mechani...
