Pulse-Width Modulation Signal Generator

Magnets don't grow in fields, but magnetic fields are important to understand. The lesson covers the effect electricity has on magnetic fields. Scholars use a compass, magnets, and electrical wire to test magnetic fields and energy...

Time to take a pulse check. The mid-module assessment allows pupils to check where their knowledge falls for the first portion of the module. The 10th resource in a series of 23 covers content from the binomial theorem to hyperbolas....

Shocking! Share the story of electric fish with young biologists for a fascinating lesson in specialized cells. The narrator of the video describes how some species of fish generate electric current, differentiates between weakly and...

This wave and electromagnetism assignment is so thorough, it could be used as a unit exam. The first section of it covers wave concepts. The next section addresses static electricity. There is a section that deals with electric circuits....

How far would you have to travel so that the light of the full sun would provide "daylight" no brighter than twilight on Earth? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and...

An MRI uses both a magnetic and electricity, so how do the two interact with each other? Class members observe the effects on a charged particle when it is subject to both an electrical and magnetic field. The teacher background...
