When using this module, you can control the electromagnet on and lff by controlling the High or Low level on its Signal end
Electromagnet built-in pure copper coil,strong conductivity,low power consumption
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
Small electromagnet induction,with high strength suction
