Abstract

An intelligent magnetic system includes a first piece of ferromagnetic material having magnetically printed field sources having a multi-polarity pattern that extend from a first side to a second side that is magnetically attached to a second piece of ferromagnetic material, where a shunt plate disposed on the first side that routes magnetic flux through the first piece of ferromagnetic material from said first side to said second side. The system also includes at least one simple machine for amplifying an applied force into a detachment force that creates an angled spacing between the first piece of ferromagnetic material and the second piece of ferromagnetic material, at least one sensor for producing sensor data; and a control system for monitoring the sensor data and managing the use of the first piece of ferromagnetic material.
