Magnetic engineering is design engineering that uses magnetic technologies. Magnetism is an integral part of electrical engineering because it is used in the creation of products such as relays, solenoids, inductors, chokes, coils, loudspeakers, motors, generators, transformers, and electricity meters. 

What are we doing with magnetic technology?

ePropelled has successfully patented numerous different innovations that use magnetic technology for propulsion motors, starter generators, and intelligent power management controllers. Our technology is a combination of motor design and software control that produces a more efficient method of electric propulsion at various torque and speed levels. ePropelled products can deliver at least a 15% improvement in efficiency and a major increase in performance. This translates into reduced cost through smaller battery packs, extended range, or a combination of the two. 

A quick lesson in magnetism

Electromagnetism is the force produced when an electrical current flows through a conductor. 

There are two forms of magnetism in magnets, permanent and temporary. Permanent magnets, ones that remain magnetized, are often used in hard drives, motors, cars, generators, televisions, phones, headphones, speakers, transducers, and sensors. Temporary magnets do not remain magnetized on their own and need the magnetic field to be created, often by an electric current running through a coil. 

Magnetic material has two poles creating invisible lines of flux around it. This magnetic field attracts and repels electric forces and when two magnetic materials are brought together an interaction occurs: 

  • They repel each other when adjacent poles are the same 
  • They attract each other when adjacent poles are opposites
