Let's see how an emf can be induced by a changing magnetic field. A circular coil of wire with 500 turns and an average radius of 4.00 cm² is placed at a 60° angle to the uniform magnetic field between the poles of a large electromagnet. The field changes at a rate of -0.200 T/s. What is the magnitude of the resulting induced emf? Figure 1 of 1> 4,00 cm/ j60° tØ =30° Part A - Practice Problem: A 390-turn coil with an average radius of 0.060 m is placed in a uniform magnetic field so that $ = 40°. The field increases at a rate of 0.295 T/s . What is the magnitude of the resulting emf? Express your answer with the appropriate units. µA E = Value Units
