A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

A disk's surface is divided into concentric tracks (circles within circles), and the thinner the tracks, the more storage. The data bits are recorded as magnetic spots on the tracks in one ...

One thing we’d suggest is switching from a disc to a cylinder with magnets placed in a Halbach array to direct as much of the magnetic field into the interior as possible, with coils of copper ...

[AnotherMaker] discovered something that might breathe a little more life into those dead disks — magnets ... a spot in the disk that is going bad, and the stronger magnetic field is required ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

Thus, understanding the magnetic fields ... around a magnet. The team thinks that the measured three-dimensional structure might create strong turbulence within the protoplanetary disk.

Given the importance of this gargantuan bar magnet in our day-to-day lives, it’s worth understanding how it works — and when it doesn’t. Since the magnetic field is sustained by geological activity ...
