In the core of a long solenoid the magnetic flux density is 100 Tesla. The cross section of the solenoid is a circle with diameter d=10 cm. Determine the magnetic flux in the core in mWb.

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. Positive nunber

Problem 2: Consider the magnetic core shown in figure P-2 and notice that three sides of the core are of uniform width, whereas the forth side is somewhat thinner. The depth of the core into the page is 10 cm. The coil has 300 turns and the relative permeability of the core is 2500. Determine the current that will produce 50 mWeb flux in the core.
