as the iron rod would need to be heated past 1418 degrees Fahrenheit. But a temporary magnet can be created using simple household materials. Temporary magnets are safe to create and use, and this can be either a fun project to do at home or a project for ...
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...
, this seems like little more than a loose collection of parts until electricity comes into the picture. but you don't have to wait for a storm to bring an electromagnet to life. a current is introduced, either from a battery or another source of electricity, and flows through the wire....
Often, the device is essentially an electromagnet. Why Magnets Stick Magnets are attracted to materials that have unpaired electrons that spin in the same direction. Shutterstock/New Africa If you've read How Electromagnets Work, you know that an electrical current moving through a wire creates...
One method is to make a magnet out ofa mixture of different types of metal. The metal is heated and melted, then placed in a cast, or container that's used to make a shape. The metal cools in the cast. Then magnetism is added to it, usually with a powerful electromagnet that's bee...
Once we figure that out, we have a better handle on how to apply them to make useful tools for us, right? Let me share with you some of what is known about how magnets work. All of the questions have NOT been answered, perhaps you will help answer some of them. So, some of ...

The Sounder: requires a bit of care in construction and adjustment. The electromagnet coil consists of one of the iron nails with at least 100 turns of the wire wound neatly around it. ( If possible wind on 200 or more turns to make the magnetic force stronger. ) ...
NIB magnets made earbud earphones possible. In order to make a tiny earphone handle enough power to make it sound good, the magnets in the audio transducers need a strong magnetic field. While earphones existed before neodymium magnets, they weren’t suitable for high-fidelity listening. The sma...
