Formula and explanation
Formula: F = B I L sinθ Applicable Conditions: A straight wire of length L with constant current I in a uniform magnetic field. θ is the angle between the wire and the magnetic field direction. Explanation: This is the result of integrating the current element formula along a straight wire. The magnitude of the force is proportional to B, I, L, and sinθ.
