A double magnet cannon is put to the test against a towering structure crafted from magnetic balls. With incredible force, the powerful magnets unleash their energy, colliding with precision to ...

To investigate, describe and recall how the strength of the magnetic field depends on the current in the coil, the number of turns in the coil and the material used as the core of the coil.

Rare-earth metals like neodymium have very high magnetic anisotropy, which contributes to the strength of rare-earth magnets. But rare-earth metals by themselves actually make pretty poor magnets ...

Iron particles effectively act as tiny magnets that can record both magnetic field strength and direction when the process of crystallization locks them in place. The researchers found that rocks ...

Astronomers have finally unlocked a crucial piece of the planet formation puzzle by detecting the magnetic fingerprint of a young star’s protoplanetary disk. Using ALMA, researchers observed how dust ...

The entire process is energy intensive, costly, and risks contaminating local water. Magnetic strength in the magnets used in electric motors is measured in tesla (where 1 tesla = 10,000 Gauss ...
