1. Two insulated wires, each 2.20 m long, are taped together to form a two-wire unit that is 2.20 m long. One wire carries a current of 7.00 Ay the other carries a smaller current in the opposite direction. The two wire unit is placed at an angle of 76.0“ relative to a magnetic field whose magnitude is 0.350 T. The magnitude of the net magnetic force experienced by the two-wire unit is 3.13 N. What is the current (No Response) 2. Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field as in the figure below. Coil 1 has a radius of 4.2 cm and rotates in a 0.15-T field. Coil 2 rotates in a 0.42-T field. Each coil experiences the same maximum torque. What is the radius (in cm) of coil 2? (No Response) cm 3. A wire has a length of 4.00 x 102 m and is used to make a circular coil of one turn. There is a current of 2.90 A in the wire. In the presence of a 3.60- T magnetic field, what is the maximum torque that this coil can experience? (No Response) Nm
