1. A 200-turn coil with an average radius of 0.06 m is placed in a uniform magnetic field so that 6 = 30°. The strength of the field increases at a rate of 0.450 T/s. What is the magnitude of the resulting emf? 0.509 V 0.881 V 0.147 V 0.441 V 2. What is the role of a commutator in an electric generator? (1 point) It carries electric current from the generator to the load. It causes the emf to vary sinusoidally. It maintains a constant sign for the emf. It maintains a uniform and constant magnetic field. 3. A single loop of wire with an area of 0.0800 m' is in a uniform magnetic field that has an initial value of 1.50 T. The field is perpendicular to the plane of the loop, and its strength is decreasing at a constant rate of 0.400 T/s. The loop has a resistance of 0.400 22. What current is induced in the loop? 0.0320 A 0.0375 A 0.0800 A 0.0480 A
