Magnetic Force

Magnetic forces are interactions between 2 moving charged objects. Additionally, if a single moving charge is in a magnetic field, the field can also exert a force on the moving charge. Magnetic force is designated by the variable

{F_B}

F_B=qvBsin(\theta)

${F_B}$ is the magnetic force exerted on the charge
${q}$ is the charge
${v}$ is the velocity of the charge
${B}$ is the magnetic field in which charge is moving through
${\theta}$ is the angle between the velocity of the charge and the direction of the magnetic field that the charge is moving through
