A long straight current-carrying wire is supported by light strings tied to the wire at regular intervals. The figure shows a cross-sectional view-in this view, the current in the wire is directed perpendicular to the page. The wire, which is horizontal, hangs at equilibrium so that the strings make a 30° angle from the vertical. The wire is in a uniform magnetic field directed down-the magnetic field has a magnitude of 0.520 T. The wire has a mass per unit length of 0.180 kg/m. We will define out of the page to be the positive direction, so you can use a positive sign in your answer below if the current is out of the page, and a negative sign if the current is into the page. What is the magnitude and direction of the current in the wire? string 30 Lcurrent-carrying wire в
