    Graduate What happens if I rotate a current-carrying wire?

    Let's assume that we have a straight current-carrying wire, along the z axis of the cartesian (or cylindrical) coordinates' system. Biot - Savart law tells as that the magnetic field at a distance r from the wire is dB=\frac{\mu_0}{4\pi}I\frac{d\boldmath{l}\times r}{r^3}, where dl is the wire...

    Current loop + perpendicular current : magnetic field?

    Homework Statement Hi, it's my first post and I'm not sure whether it's the right category to post anyway. Please help me though :) I have to "construct" theoretically a superposition of magnetic fields for the introduction of my tokamak-related diploma thesis. First task was to find the...
