This total force on all the moving free electrons is the force on the current carrying conductor placed in the magnetic field. Magnitude of the force. The magnitude of the force is F = BIl sin θ. If the conductor is placed along the direction of the magnetic field, θ = 0o, Therefore force F = 0. If the conductor is placed perpendicular to the magnetic field, = 90o, F = BIl. Therefore the conductor experiences maximum force. Direction of force Since this force exists whether or not the charges are moving, it is sometimes called the electrostatic force. Magnetism could be said to be an electrodynamic force, but it rarely is. The combination of electric and magnetic forces on a charged object is known as the Lorentz force.
