Strong lab magnet 10 Tesla 100,000 Gauss Surface of neutron star 100,000,000 Tesla 10^12 Gauss Magstar 100,000,000,000 Tesla 10^15 GaussWhat is a Tesla? It is a unit of magnetic flux density. It is also equivalent to these other units: 1 Weber per square meter 10,000 Gauss (10...
Originating from Earth’s core and atoms themselves, magnetism is the invisible force that shapes our everyday lives. Here’s how magnets actually work.
Magnets are usually made of metal iron, or another material that has lots of iron in it, such as steel. Magnets can be of various shapes, but all of them have the ability to pull things towards themselves. This invisible force is called magnetism. Magnets only attract (pull) metals that ...
Diamagnetic and paramagnetic effects are caused by quantum-mechanical effects (just like ferromagnetism) but are very weak compared to ferromagnetism. However, with a strong enough external magnetic field diamagnetic and paramagnetic objects can be repelled and attracted, respectively. For example, a ...
However, hard magnetic materials will keep most of their domains aligned, making it a strong permanent magnet. Magnetic field lines are closed loops. They enter a magnet at its South pole, and exit a magnet at its North pole. The poles may cover a large area, where the concentration of ...
Alnico magnets: These were developed in the 1930s and are made from aluminum, nickel and cobalt. They're stronger than ceramic magnets, but not as strong as the ones that incorporate a class of elements known as rare-earth metals. Neodymium magnets: These contain iron, boron and the rare-...
A strong magnetic field is produced when the electron magnetic moments of a material are aligned. When they are disordered, the material is neither strongly attracted nor repelled by a magnetic field. What Is a Magnet? A magnet is any material capable of producing amagnetic field. Since any ...

From the compass to electricity, the accidental discovery of magnetic rock altered the course of humanity way beyond decorative refrigerator magnets.
Magnets that are strong enough to penetrate deep enough to help many conditions are strong enough to pinch you between them selves and another magnet or iron or steel object. The force of this collision may be 50 or 100 pounds and has often cut my garments and flesh and a few times other...
