Question
Please answer part C with detailed explanation. I am not sure how to find the direction of the current in coil 2. How do I find the direction of the current in coil 2? Thanks!
CHAPTER 23 REVIEW - MOTIONAL EMF AND INDUCTION Lenz's Law - Conductors produce currents to oppose a change in magnetic flux r supply is connec through the coil. A second coil consisting of 100 turns of wire, with a radius of 5cm, is connected to a computer interface, used to plot the emf in coil #2 as a function of time. rant a) Initially the current in coil 1 is a constant 20x103 A. What is the emf in m) coil #2 ? b) Next, current in 1 increases linearly supply Power coil #2 with time so that the field at coil 2 due to coil 1 increases at a rate of 0.02 T/s. What is the emf in coil 2? c) What is the direction of the current in to compule interface coil #1 coil 2?Explanation / Answer
Q1, Part (C)
Ans- opposite to the direction of current in coil 1.
Since, Direction of current in coil2 will be such that it will oppose the induced emf in it or we can say that direction of magnetic field due to current in coil2 will be such that it will oppose the changing magnetic flux in it.
