Instead of relying on plasma currents like tokamaks, stellarators confine the plasma by specially shaped 3D magnetic fields.

The NSTX-U is the primary nuclear fusion reactor experiment which is ongoing at the US Department of Energy's PPPL.

The field inside a solenoid is strong and uniform. The small magnetic field caused by the current in each coil add together to make a stronger overall magnetic field. Figure caption, A solenoid ...

(The magnets underneath create a strong magnetic field and keep the magnets ... The paper clips will form a cradle for the coil. Attach one end of the coil to one paper clip and the other end ...

Permanent magnet degaussers are available in both manual (handheld) and drawer styles. As their name suggests, they use materials called permanent magnets instead of coil-based electromagnets.

The procedure involves a magnetic coil that is placed over the scalp. Repetitive magnetic pulses emanate through the coil, enter the brain, and activate neurons in targeted regions, such as those ...

Repetitive transcranial magnetic stimulation offers rapid depression relief for patients unresponsive to conventional treatments. Accelerated over just five days, this therapy targets key brain areas ...

The design uses a coil of copper wire in a 3D-printed plastic housing, surrounded by a claw full of strong magnets ... rather than a single monolithic magnet. It’s possible to get more capacity ...

The ‘Hi-X’ bit of the model number means ‘high excursion’, and the Hi-X20 use the same 44mm full-range dynamic driver ...

When the coil is powered up, any metal within is quickly and evenly heated by virtue of the strong magnetic flux in the coil. To use the shrinker, [Roetz 4.0] starts with a scrupulously clean tool ...

Induction cooktops work through electromagnetic energy that runs through copper coils underneath the glass surface ... As long as there is a strong magnetic base on your cookware, you can still cook ...

The field inside a solenoid is strong and uniform. The small magnetic field caused by the current in each coil add together to make a stronger overall magnetic field. Figure caption, A solenoid ...
