Formula and explanation
Formula: B = (F)/(I Δ l sin θ) or F = I Δ l × B. Conditions: Straight current - carrying conductor, infinitesimal current element Δ l, uniform or locally uniform magnetic field. Explanation: This formula defines the magnitude and direction of the magnetic induction B. F is the Ampere force on the current element I Δ l, θ is the angle between the current direction and the magnetic field direction. The direction of B is determined by the vector cross product (right - hand rule).
