Pulsed electromagnetic propulsion system
View Patent ↗The present invention discloses propulsion system operating exclusively in electromagnetic domain. Only electromagnetic field and direct electric current are used to generate propulsion force. In exemplary embodiment two switchable electromagnets, one to generate electromagnetic field, the other to generate electromagnetic force are used. To disable electromagnetic reaction force on electromagnetic field generator, streams of independent but synchronized direct current pulses passing through two electromagnets are organized in the way that first electromagnet is always carrying current when magnetic field generated by second electromagnet reaches it, thus generating Laplace force, whereas, second electromagnet is never carrying current (open circuit) when magnetic field generated by the first electromagnet reaches it, which means, no Laplace reaction force ever occurs on second electromagnet. The system therefore does not depend on the emission of matter. Only electric current is needed.
