Dublin, Oct. 12, 2022 (GLOBE NEWSWIRE) -- The "Neodymium-Iron-Boron Magnet Market: Global Industry Trends, Share, Size, Growth, Opportunity and Forecast 2022-2027" report has been added to ...

Torque is produced by the magnetic field across the air gap between the two ... SmCo magnets become more suitable. A general rule of thumb: For applications less than 240°F, NdFeB magnets are best.

The miniature electromagnet was created by MagLab engineer Seungyong Hahn. It generated a world-record 45.5 tesla magnetic field — more than 20 times the strength of a hospital MRI magnet.

Magnetic interference was observed at skin-to-magnet distances of up to 3 cm, with a mean maximum interference distance of 2.1 cm for pacemakers and 1.7 cm for ICDs (p=0.007).

This creates a tiny repulsive force toward the magnet that, again, disappears without the magnetic field. So, under everyday conditions, we would never notice that paramagnetic and diamagnetic ...

Save guides, add subjects and pick up where you left off with your BBC account. A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron ...
