However, some phenomena that underlie magnetism continue to elude scientific explanation. Exactly how do magnets work? Large-scale magnetism, like the kind observed in bar magnets, results from magnetic fields
How does a magnetic field create electricity? How can a magnetic field produce an electric current? How do magnets create a magnetic field? How does magnetism work at the atomic level? Why is magnetism a force? How does electricity create the magnetic field?
How do semiconductor ionizing radiation detectors work? How does a magnetic field create electricity? How does magnetism work? How do you charge an electroscope by conduction? How does induced magnetism work? How are electromagnetic waves measured?

This current generates a magnetic charge, and this natural magnetism of the Earth is what makes a compass work. A compass always points north because the metal needle is attracted to the pull of the North Pole. Electromagnets All Around Us Many electromagnets have an advantage over permanent ...

Even though the ceramic magnet has been around for so long, they weren't commercially produced until 1952. Although they're common and keep their magnetism, they tend to have a weaker magnetic field (known as the energy product) than other types of magnets. Alnico magnets: These were ...
Rather, demagnetizers only offer a temporary period of magnetism, after which the screwdriver will revert back to its nonmagnetic properties. To remove magnetic fields from tools, demagnetizers expose them to an irregular magnetic field. This causes the electrons within the tool to become misaligned...
Although no one is sure why the corona is so hot, it is thought to be caused by the sun's magnetism. The corona has bright areas (hot) and dark areas called coronal holes. Coronal holes are relatively cool and thought to be areas where particles of the solar wind escape. The Sun's...
When I click save, how does it work? The spindle rotates the platter. The actuator arm makes a cross-over motion across the plate. The actuator arm sends your saved data to the read/write head. The head alters the polarity of a sector (a section of the platter - see below) on the...
