You have a solenoid with an initial current of 386 A and a turn density of 6088 loops m What is the initial magnetic field through the solenoid? Binitial = 2.95 ✔T The current in the solenoid drops to 51 A over the course of 1.1 ms. What is the final magnetic field through the solenoid? Bfinal= T Inside the solenoid is a coil with 75 loops and a radius of 9.0 cm. The coil is aligned so that the magnetic field from the solenoid passes through the coil perpendicular to the plane of the coil (directly down the center of the coil). What is the magnitude of the induced emf in the 75-turn coil at the center of the solenoid during this change in magnetic field? Enter you answer as a positive number. emf= V The coil has a resistance of 20 2. What is the current through the coil? Icoil = A What is the power dissipated by the coil? Pcoil = W

Expert Solution
Introduction:
Disclaimer: “Since you have asked posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get remaining sub-part solved please repost the complete question and mention the sub parts to be solved.”
We are given current in solenoid. We are also given turn density of solenoid. We first find magnetic field for this case. We then again find magnetic field for the reduced current case. We then find emf induced in the coil kept inside solenoid.
