What is the change in the form of energy that is shown by the change in direction of the compass needle when an electric current is passed beneath it?
When the magnet is moved inside the coil of wire, what does the Galvinometer indicate?
Would making the fixed magnet stronger, have an effect on the amount of current produced?

I. As shown below, a coil is in a magnetic field that is directed upward. If the magnitude of the magnetic field increases, in what direction does the induced current flow in the coil? Explain 2. Suppose you know that a deflection of the galvanometer needle to the right means that current is flowing into the galvanometer as indica ted A bar magnet is moved towards a coil as shown in the picture below. The galvanotneter needle deflects to the...

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...

1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1. Describe the direction of the compass needle as you moved...

galvanometer. Use the cylindrical magnet to generate a changing
magnetic field around the coil and note the reading of the
galvanometer as the field changes. Thrust the N pole of the magnet
into the coil and note the effect on the galvanometer. When the
needle has come to rest, withdraw the magnet as quickly as
possible. Note the effect on the direction of current flow. Reverse

If a needle is moved away from north and then, released, what will happen? The answer is that "magnetic dipoles twist to align with the magnetic field", My question is: does not having a magnetic dipole moment mean that a current must be running through the compass needle since the magnetic dipole moment is produced by a current running through a wire?

Objective: In this lab you will investigate magnets, electromagnets, electric motors, generators, and magnetic inductance and discuss their applications. Part 1: Magnetic Fields How do the lodestone and round magnet affect the compass needle? How can you tell which side is North and South? How is an electromagnet similar to a permanent magnet? How is it different? Part 2: Electric Motors Describe how a DC electric motor works. Part 3: Magnetic Induction In the setup with a gilley coil connected...

in a lecture demonstration, a bar magnet is moved toward a 2,000 "turn" circular coil such that the magnetic field is perpendicular to the area inside of the coil and increases uniformly from 20.0mT to 130.0 mT in 0.250 s. The diameter of the turns is 15.0 cm and the entire coil has a resistance of 3.00 ohms. What is the current induced in the coil and how much energy is produced as "Joule heat" in the wire turns over...
