Homework Answers
1.) The direction of current in the wire is from right to left. This is according to the right hand rule.
2.) Magnetic field around a current carrying wire is inversely proportional to the distance of point from the wire where magnetic field is calculated.
Hence, magnetic field magnitude will be larger at point 1 because it is closer to the wire than point 2.
3.)
(a.) Voltage will be induced a Ross the coil.
This is because when the coli is rotated, the magnetic flux through the coil changes. Hence, emf (voltage) will be induced.
(b.) Voltage will be induced in the coil.
When the coil is moved quickly away from the magnet the magnetic flux through the coil changes because magnetic field is inversely proportional to the distance from the magnet. Hence, voltage will be induced.
(c.) Voltage will not be induced in the coil.
Since the magnet is sitting at rest inside the coil, the magnetic flux through the coil will not change. Hence, voltage will not be induced.
(d.) Voltage will be induced in the coil.
When the magnet is pulled away from inside the coil, the magnetic flux through the coil will change. Hence, voltage will be induced in the coil.

General Physics 2 w/o calc
Now suppose that the battery is removed and replaced with an ammeter. No current will flow through the wire because there is no energy source. Consider what will happen when a barmagnet is pushed toward the coil as shown in the figure below. When the coil "feels" the changing magnetic field caused by the approach of the bar magnet, it will thereby become energized; a current will begin to flow through it, and the ammeter will register that current. This...

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...
