Força magnética
O sentido está sempre de acordo com a regra da mão direita, então Fmag
"brota" da palma da mão.
Usamos pensando em uma carga positiva. Quando for negativa o sentido da força será oposto ao obtido.
a intensidade da força é dada por Fmag=∣q∣ ⋅v ⋅B ⋅sinθ

Pontos importantes
Se
θ = 0° ou 180° então a força magnética é nula. O campo magnético, portanto, não atua em partículas que se move em sua direção.Se v = 0 então a força magnética também é nula.
Se θ= 90° então a força magnética é máxima e igual a Fmag=∣q∣ ⋅v⋅B
Se q = 0 então a força magnética é nula
