Magnetic field due to a current

WebWe have learned about the existence of a magnetic field due to a current-carrying conductor and the Biot – Savart’s law. We have also learned that an external magnetic field exerts a force on a current-carrying conductor and the Lorentz force formula that governs this principle. Web20.6. This equation gives the force on a straight current-carrying wire of length ℓ in a magnetic field of strength B. The angle θ is the angle between the current vector and the magnetic field vector. Note that ℓ is the length of wire that is in the magnetic field and for which θ ≠ 0, as shown in Figure 20.19.
