**Magnitude of the force** is defined as the sum of all the forces acting on an object. The equation below is the sum of N forces acting on an object.

The magnitude of the force is F = BI*l* sin θ

(i) If the conductor is placed along the direction of the magnetic field, θ = 0o, Therefore force F = 0.

(ii) If the conductor is placed perpendicular to the magnetic field,

θ = 90o, F = BI*l*. Therefore the conductor experiences maximum force.
