    Covariant derivatives commutator - field strength tensor

    Homework Statement So I've been trying to derive field strength tensor. What to do with the last 2 parts ? They obviously don't cancel (or do they?) Homework EquationsThe Attempt at a Solution [D_{\mu},D_{\nu}] = (\partial_{\mu} + A_{\mu})(\partial_{\nu} + A_{\nu}) - (\mu <-> \nu) =...

    Perpendicular wires carrying current, torque

    Homework Statement Two thin wires of length L_1, L_2 were placed perpendicular to each other in half of their lengths. Wires are carrying current I_1 and I_2. Find the torque on each of those wires. Homework Equations \tau = \mu \times B = r \times F The Attempt at a Solution To...
