Question
In a region that contains multiple current-carrying wires, the net magnetic field at a given point, P, is the VECTOR SUM of the magnetic fields produced by EACH wire at that point. Bnet = B₁ + B₂ + ... = ΣB₁ where B; is the field produced by the ith wire at point, P. For a given wire, the direction of its magnetic field will be tangential to its circular field lines, which curl around the wire as given by the RHR for Magnetic Fields as shown. B Food!
