FUERZA MAGNÉTICA SOBRE UNA CARGA ELÉCTRICA

Sobre una carga eléctrica en movimiento que penetre en un campo magnético, B, experimenta una fuerza denominada fuerza magnética. La fuerza magnática siempre es perpendicular al plano formado por la velocidad y el campo magnético. Ésta modifica la dirección de la velocidad, sin modificar su módulo.

 Magnitud de la fuerza magnética: 

  

F_m = qvBsenθ

 
Fm = Fuerza magnética [N]

q = Valor de la carga [C]

v = Velocidad [m/s]

B = Campo magnético [T] (Tesla)

θ = Ángulo [grados o radianes] entre el campo magnético y la velocidad de la carga

La dirección de la fuerza se obtiene aplicando la regla de la mano derecha
