An electro magnetic properties, electromagnetic forces and electromagnetic signals used device system embodied with electromagnetic ,distance, and proximity ,and speed sensors to prevent and avoid collisions of new ,&old automobile vehicles, Trains, aero planes and for several Army defense safety applications( solders safety & for Army) by use of electromagnetic forces, signals and properties. The electromagnetic properties and forces, signals ,used device system to prevent and or avoid collisions along with improvised features ; includes a plurality of mobile vehicles, objects, trains, aero plans static skyscrapers each having a body having an inner& outer surface with Ferro magnetic & electromagnetic materials surface interfaced with surrounding & opposite vehicles, objects there by respective action will takes place according to various users pre, post defined conditions & functions. Each of a plurality of our designed device is electro magnetized by the power supply by non renewable energy sources like solar, wind, or light focus of the other vehicles (light energy) and has the switching polarity and varying electro magnetic polarities, fields, properties, by the feedback signals, alerts, controlling, automated predefined action will takes place by using the data from user, authorized defined actions and mechanism. Vice versa. Fig-1
