Unit 12: Magnetic effects of electric current 1,200 possible mastery points Mastered Proficient Gravitational fields affect masses, electric fields affect electric charges, and magnetic fields affect magnetic materials or magnets. So to summarize, how do magnets push and pull each other over a distance? Let's practice some problems involving Fleming's left hand rule to find out the direction of the force on a current in a uniform magnetic field. Instead, the magnetic force acts through a magnetic field. The strength of the magnetic forces two objects exert on each other depends on the strengths of the magnets, their orientations, and the distance between them.
