    • 9.1: Introducción al Potencial Magnético
      La fuerza sobre una carga q en un campo magnético es Qv×b. Esta fuerza (la fuerza de Lorentz) no depende sólo de la posición de la partícula, sino también de su velocidad (velocidad y dirección). Por lo tanto, la fuerza no es conservadora. Esto sugiere que tal vez no podamos expresar el campo magnético meramente como el gradiente de una función de potencial escalar —y esto es correcto; no podemos.
    • 9.2: El potencial del vector magnético
    • 9.3: Conductor largo, recto y portador de corriente
    • 9.4: Solenoide Largo
    • 9.5: Divergencia
      Al igual que el propio campo magnético, las líneas de potencial vectorial magnético forman bucles cerrados (excepto en el caso del cable conductor recto infinitamente largo, en cuyo caso son líneas rectas infinitamente largas). Es decir, A no tiene fuentes ni sumideros, o, en otras palabras, su divergencia es en todas partes cero.
