While this isn’t the first time magnet implants have been mentioned ... Ear implants are the next most useful because oscillating magnetic fields can be translated to sound.

For instance, in maglev trains, powerful superconducting magnets create a strong magnetic field with diamagnetic ... eddy damping', which occurs when an oscillating system loses energy over ...

"We apply an oscillating field to reset the magnetization ... allows users to predict the bending behavior of magnetic cilia based on hard magnets, depending on the orientation of the cilia's ...

But, there may be another way, albeit a rather special case, where a magnet can not only be levitated, but locked in place using a rotating magnetic field. The video shows a demonstration of how ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

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 ...

An open-transmit and 24-channel flexible receiver head coil enhances ultrahigh-field fMRI, enabling sub-millimeter resolution for somatosensory and motor cortex mapping, advancing neuroscience and ...
