일반물리학 2 — Magnetic Fields Due to Currents: Problem 10

10 In Fig. 29-29, five long parallel wires in an xy plane are separated by distance d = 8.00 cm, have lengths of 20.0 m, and carry identical currents of 3.00 A out of the page. Each wire experiences a magnetic force due to the currents in the other wires. In unit-vector notation, what is the net magnetic force on (a) wire 1, (b) wire 2, (c) wire 3, (d) wire 4, and (e) wire 5?
