Common questions
What is the Magnetic Force on Charge formula?
Magnetic Force on Charge is written F = qvBsinθ. Magnetic force on moving charge (Lorentz force). It belongs to Electricity & Magnetism, under Magnetism.
What are the units in F = qvBsinθ?
In SI units, F is magnetic force, measured in kg·m/s²; q is charge, measured in A·s; v is velocity, measured in m/s; B is magnetic field, measured in kg/(A·s²); θ is angle, measured in rad.
How is the Magnetic Force on Charge formula derived?
F = qv × B, magnitude |F| = qvB sin θ. The result is F = qvBsinθ.
