US 2020/0051722 A1 · SYSTEM AND METHOD FOR GENERATING A MODULATED MAGNETIC FIELD

Abstract

A system comprising a solenoid electromagnet for generating a magnetic field and a driver circuit coupled to the solenoid electromagnet for modulating the magnetic field generated by the solenoid electromagnet. The magnetic field generated by the solenoid electromagnet of the present invention exhibits improved control over the direction and projection of the generated magnetic field. The generated magnetic field has the ability to detach permanent magnets from metal plates, cause motion of permanent magnets and soft magnetic materials as well as create separation between two magnetically bound permanent magnets.
