Magnets on a Stick: A Magnetic Force Demonstration Device

Emerging electricians build a simple ammeter for making measurements on an electric current. They test the placement of solar cells in both series and parallel circuits and examine the magnetic field produced by the movement of electrons...

The compass was first used in 206 B.C., but we didn't discover magnetic poles until 1263 A.D. Presentation begins with the history of magnetism before continuing on to magnetic fields, magnetic forces, electromagnets, currents,...

Students explore the properties of magnets by designing a device that can move as far as possible using only magnets to move it, and design a machine that will stay in motion for the greatest period of time.

This set of seven activities attracts physical science stars to concepts concerning magnetism. Pupils play with a lodestone, magnets, needles, and iron filings to understand magnetic forces, fields, and applications. If you are new to...

Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...

Drive an electric current through a coil of wire and show how it can pull a nail right into its core. This vivid demonstration exhibits the electromagnetic field. Consider also showing your class a few of the devices that make use of...

Help your young scientists learn which materials are affected by magnetic fields with an activity that presents the information about different types of materials — diamagnetic, paramagnetic, and ferromagnetic — and their interaction...

 The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform tests to...

Exploratorium Science Snacks are miniature science exhibits and experiments that can be made with common, inexpensive, easily available materials. These electricity snacks represent a set of devices that you can build and experiment with...

Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is created...
