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.

The primary side of a Tesla coil is usually a handful of turns of thick wire to handle the current without melting. This build runs at two or three amps, giving a primary power of around 150 Watts.

What do a Rogowski coil, a magnetic core, and a hall effect sensor have in common? They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage ...

When you push the magnet through the middle of the coil, an electric current is produced in the wire. The current flows in one direction as the magnet is pushed in, and in the other direction as ...

Precision-engineered induction coils are key to achieving reliable and efficient performance in induction heating systems.

Abstract: To guarantee safe switching of the expensive medium voltage (MV) device with limited durability, the overcurrent protection scheme based on Rogowski coil current sensor (RCCS) is the ...
