1. A square loop of wire (10-cm each side) hangs vertically, as shown here. When the current in the wire is 0.245 A counterclockwise, a scale supporting the wire indicates a downward force of 3.48x10 N. Find the magnitude of the magnetic field. I B O O O O 2. In which direction is the (conventional) current in the wire moving? In which direction is the magnetic field in the vicinity of the wire? In which direction is the magnetic force on the wire?
