Electromagnets

Electromagnetic Specifications

Electromagnets are comprised of three main elements to produce a magnetic field when powered: a core, coils, and a current source. Their general purpose is to provide a magnetic force for a mechanical application. The field can be manipulated by a change in supplied voltage, current, core material, or the number of wire loops. Complimentary to permanent magnets, they can be switched off and don’t require special rare earth materials. The three main types of electromagnets are Low Frequency AC, DC, and Pulse.

  • Constantly maintains magnetic field without a drop in strength
  • Doesn't require a power supply or source
  • Can feasibly achieve higher strengths
  • Can be designed to be lightweight and have a smaller footprint
  • Overall, can be a cheaper solution (especially since no power is needed to run/operate), no maintenance or cooling required
