The scientists discovered that adding a magnetic coating to green algae micro-swimmers had minimal impact on their swimming ability. The algae — using a breast-stroke motion with their flagella — ...

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 ...

He noticed that he could keep the pendulum moving at a pretty good tick if he triggered the magnetic coil every third pass, so he implemented an Arduino to keep count of passes and apply the ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

But present magnetic bottles are unstable. They bulge and flutter, permitting their contents to escape. More current would produce stronger magnetism. But if coils are fed too much current ...
