Magnetic Induction 1. You have two loops of wire that are parallel to each other (one...
For this station, you have two coils of wire (each with different numbers of loops), a magnet, some connecting wires, and a galvanometer. A galvanometer is an ammeter that measures very small currents (micro-amperes) and indicates the direction of that current. Understanding how the meter behaves is important here, because you’re going to use the meter to determine/measure current—including its direction. For this galvanometer, when (conventional) current enters the terminal on the right (as viewed when reading the dial), the...
The figure shows two parallel loops of wire having a common
axis. The smaller loop (radius r ) is above the larger
loop (radius R) by a distance x >> R.
Consequently, the magnetic field due to the counterclockwise
current i in the larger loop is nearly constant throughout
the smaller loop.
Suppose that i, the current in the larger loop is shut
off, and decreases at the constant rate
di/dt.
(a) Find an expression for the magnetic flux
through...

A vertical bar magnet is dropped through the center of a horizontal loop of wire, with its south pole leading. At the moment just before the south pole passes through the loop, what is the direction of the induced current in the loop (viewed from above)? 2. Explain your answer to the previous question. 3.

4. Two concentric wire loops lie in the plane of the page. Loop A carries a current IĄ counter-clockwise (Assume that each wire loop forms a closed circuit so that current is able to flow. Each wire has some small non-zero resistance.) loop A loop B (3 pts. total; - pt. per error) What direction of current would EACH of the following actions induce in loop B? Consider each situation SEPARATELY and INDIVIDUALLY from the others Choose from the following...
Two long current-carrying wires are parallel to each other and both are tilted upward (the two wires are still parallel to each other). The two wires have the same current going in the same direction. Which of the following arrows on wire #1 is the direction of the magnetic force on wire #1 due to wire #2? Note: a and care perpendicular to the wire. b #1 a #2 с None of the four arrows is in the direction of...
