An electric field refers to the area around an electrically charged particle. The SI unit of an electric field is expressed in Newton per Coulomb or Volts per meter. Also, the force expressed in an electric field is proportional to the electric charge. The electric field is equivalent to the electrical load. The electric field is perpendicular to the magnetic field of a particle.
A magnetic field is a field of force surrounding a permanent magnet. It is obtained by moving electric charges. The strength of an electric field is expressed in Gauss or Tesla. A magnetic field is proportional to the speed of electric charge. It is perpendicular to the electric field of a particle.
