The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly ...

Cutting a bar magnet in half won't get rid ... like refrigerator magnets, are known as permanent magnets. In these materials, the magnetic fields of many atoms in the material have become ...

As noted in the paper by [P. Helander] et al., the use of permanent magnets can substantially simplify the magnetic-field coils of a stellarator, which are then primarily used for the toroidal ...

As you saw in your paperclip experiment, not all magnets are permanent magnets. Electromagnets are a different type of temporary magnet. The magnetic field of an electromagnet only exists when an ...

The job of a catalyst is to ultimately speed up reactions, which could reduce an hour-long process into several minutes. It ...

The alternating magnetic field generates electricity within the ... Since magnetic particles are sprinkled throughout the gallium, a permanent magnet can drag it around. In solid form, a magnet ...

This happens because of magnetic filed. Magnetic field is a region of space where the magnet exerts a magnetic force on any other magnetic objects or moving electrically charged particles.
