Electrical current going round and round,produces a magnetic field. After a demonstration of the magnetic field surrounding an electrical wire, class members use the provided formula associated with Biot-Savart's Law to calculate the...

Focused little scientists will flitter their arms back and forth across the room with excitement as they learn the life cycle of a butterfly and how living things grow and change over time.

Help your class find the the magnetic field of a toroid, a solenoid bent into a circle with an activity that allows the class to see how a loop of wire carrying an electrical charge behaves much like a magnet. The resource provides...
