Sobre este recurso...

"Magnetic fields are vector fields associated with magnetic forces. Magnetic fields are generated by Hard Ferromagnets. Unlike electric fields, magnetic fields always make closed loops and are never created nor destroyed. Though magnetic field lines go out of north poles and end at south poles, within the magnet they form a closed loop. The closer together the field lines are, the stronger the field. When opposite ends of two magnets interact, their field lines connect the north pole of one with the south pole of another, and the two attract. When the same ends of two magnets interact, they repel because the lines cannot cross and are compressed by each other. " Fuente: BrightStorm
