Magnets & Motors

Author: Jared Wa1anoff

Motors & Magnets

After this lesson you will be able to:

Describe the magnetic field produced by current in a straight conductor and in a solenoid.

Use the right-hand-rule to determine the direction of the magnetic field in a current-carrying wire.

Given the force on a charge in a magnetic field, determine the strength of the magnetic field.

Determine the magnitude and direction of the force on a wire carrying current in a magnetic field.


 

You will, on your own, with your device will explore the relationship between magnetic fields, electric current, and the forces applied therein.  Look for a pattern that allows for the prediction of motion, current flow, and magnetic field direction.  Using these predictive behaviors, you will be able apply the Right-Hand-Rule to motors, generators, and galvanometers alike.

 

You need to take (at minimum) one full page of notes based on the PowerPoint and lesson.

You will watch the short clip on motors and generators.

Take the quick quiz to check for understanding.

Then  proceed to work collaboratively on your own devices to create and edit a slide presentation explaining how to use the Right Hand Rule for a coil of wire and how that applies to motors or generators.

Tomorrow you will finish by previewing the other groups’ presentations and filling out the feedback critique form.
