Description: This module mainly contains an electromagnet. A magnet that generates a magnetic field from an electric current. It uses the principle of electro-magnetic. With a straight metal wire passing through the current, the space around the wire will produce a circular magnetic field. In order to concentrate the magnetic field, the coil inside the electromagnet is wound into a coil, and many lines are arranged side by side, so that all the magnetic fields of the coil pass through the center of the coil. Forming a magnetic field there,which can make it absorb a 1kg ferromagnetic. When using this module, you can control the electromagnet on and lff by controlling the High or Low level on its Signal end. Small electromagnet induction,with high strength suction. Electromagnet built-in pure copper coil,strong conductivity,low power consumption. Electromagnet electric iron shell,less remanence,integrated molding,good magnetic conductivity. Package Includes: 1 Piece Keyestudio Electromagnet Module
