The magnetic circuit shown below has mean magnetic path of 0.5 m, a relative permeability of 1000, and a uniform cross sectional area equal to 5×104 m². The coil has 120 turns and, when connected to a 120 v, 60 Hz voltage source, draws 5 A. Determine the inductance of the coil in Henry. Give your answers correct to 3 decimal places. Answer:

For the series RL circuit shown in the figure below, answer the following questions and justify your answer.If the current is kept constant, does the coil have inductance?If the current is kept constant, does the coil affect the current value?Can the reverse emf ever be greater than the battery emf?

If a wire or coil with an open circuit is moved through a magnetic field . O nothing will happen O a current will be generated through the coil O it depends on the speed O an EMF will be generated in or across the coil

You have a solenoid with an into all current of 577A and a turn dentistry of 6601 loops/m What is the intial magnetic field through the solenoid ? the current in the solenoid drops to 34 A over the course of 4ms. What is the final magetic field through the solenoid ? the coil has a resistance of 20. What is the current though the coil? what is the power disssipated by the coil? inside the solenoid 56loops and a radius of 6.2cm. What is the magnitude of the induced in the 56 turn coil.
