What is the similarity between electrostatic and magnetic forces?

Similarities between magnetic fields and electric fields:

  • Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). 
     
  • Like poles repel; unlike poles attract 
     
  • Electric field points in the direction of the force experienced by a positive charge. Magnetic field points in the direction of the force experienced by a north pole.
