Magnetic field from current in wire
Web$\begingroup$ Yes, the r in the Biot-Savart integral has to be taken from every current element to P, and for all the current elements that don't lie on that top line, r should not be parallel to dl, the direction of current for that element, so in that case the cross-product will be nonzero. It might be interesting to consider the case of a 1D wire though--the … Web5 nov. 2024 · For a wire exposed to a magnetic field, τ = NIABsinθ describes the relationship between magnetic force (F), current (I), length of wire (l), magnetic field …
