15) Three current-carrying wires are perpendicular to the page. Their intersection with the page makes an equilateral triangle (each angle is 60 degrees!). The magnitude of the currents are the same. IA and Is are out of the page and Ic is inside the page. A) Find the direction of the magnetic field produced by lA and Is at the location of Ic. The correct directions of the vectors are important. B) Use superposition to find the direction of the total magnetic field at the location of Ic. C) Using the right hand rule, what will be the correct direction of the total magnetic force acting on Ic
