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 — ...

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 ...

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 ...

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.
