Magnetic Field Magnitude

This calculator uses the following equation:

B = F / (Q * v * sin(A))
B = F/ (Q*v) [If v is perpendicular to B]

• B = Magnetic Field Magnitude
• F = Force
• Q = Stationary positive charge
• v = Velocity
• A = Angle of velocity in relation to B

Note that when the velocity is perpendicular to the magnitude of the magnetic field that you can eliminate the end of the formula because the sin of 90° is 1.
