The solenoid seen above uses a body milled from HDPE and wrapped with magnet wire. The slug in the center is steel, with a few rare-earth magnets at the top. When you run current through the coil ...

It is a normally closed valve, designed to stop the flow of refrigerant when its coil is de-energized and allow full refrigerant flow when energized. On systems with a single evaporator and condensing ...

Solenoid engines are an exciting and fun project to build. In this video, we will create a powerful solenoid engine using LEGO. The basic concept involves an electromagnet that pulls a piston into 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.
