This charge controls the magnetic field, making the like charges repeal and the opposite charges attract. Compare and contrast how both a light bulb and voltmeter can be used to show characteristics of the induced current. By coiling a current carrying wire, you can concentrate the magnetic field in the center of the coil.

Design an experiment to test how field strength varies with the number of coils. Using your graph, what is the relationship between magnetic field strength and position. They can decide how much distance the force will be applied for. The Red lead faces the left side of the coil and as the compass is moved towards the upper center part of the coil, the compass is parallel to the coil.

The y-component of the magnetic field is zero along the axis of the coil. Students will change the starting height of the ball and see how this affects the amount of energy lost and the percent of the original energy lost.

How many complete rotations does the compass needle make when the compass is moved once around the coil. Voltage Field Strength Current 0 0. Make sure to label the axes and title the graph. Play with the voltage slider and describe what happens to the current in the coil and the magnetic field around the coil.

Is your graph symmetric. Identify equipment and conditions that produce induction.

How many complete rotations does the compass needle make when the compass is moved once around the coil. Number of Coils Magnetic Field Strength 1 Voltage Field Strength Current 0 0. The magnetic field rotates degrees when the battery slider moves from one side of the battery to the other.

Compare and contrast bar magnets and electromagnets. A magnetic field is being produced by the flow of electrons in the wire. As the compass needle moves closer to the coil, the strength of the field increases.

Faraday's Electromagnetic Lab

The simulation can be used to replace or supplement experiments with real equipment in lecture demos, labs, and tutorials. Relate magnetic field strength to distance quantitatively and qualitatively.

Students can adjust the strength of the force. Recall that voltage is directly proportional to current…. Number of Coils Magnetic Field Strength 1 Be sure to take all of your values along the axis of the coil.

Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow.

View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude.

You can also play with electromagnets, generators and transformers! PhET is a suite of research-based interactive computer simulations for teaching and learning physics, chemistry, math, and other sciences. PhET simulations can be run online or downloaded for free from the PhET elonghornsales.com simulations are animated, interactive, and game-like environments where students learn through exploration.

Ever wonder how a compass worked to point you to the Arctic? Explore the interactions between a compass and bar magnet, and then add the earth and find the surprising answer!

Vary the magnet's strength, and see how things change both inside and outside. Use the field meter to measure how the magnetic field changes.
