It is just magnetic. This resource presents the concept of Earth's and another planet's magnetic field and how spacecrafts detect them. Learners study a problem using magnetometers and participate in three experiments to come up with a...

Young scientists build their own electromagnet and test it by picking up paperclips. Analysis questions evaluate knowledge at the end of the activity. 

A bar magnet model built by placing a group of magnetic dipoles along the magnet. This simulation shows the magnetic field of a bar magnet, and has a movable compass which shows the magnetic field values.

Easy-to-read information and an illustration of an "electromagnet," a type of magnet in which the magnetic field is induced by the flow of an electric current.

Joseph Henry was an American scientist who pioneered the construction of strong, practical electromagnets and built one of the first electromagnetic motors. During his experiments with electromagnetism, Henry discovered the property of...

Find out more about German physicist Wilhelm Weber, who developed and enhanced a variety of devices for sensitively detecting and measuring magnetic fields and electrical currents.

Spurred by Hans Christian Orsted's discovery of a relationship between electricity and magnetism, German chemist Julian Schweigger immediately began tinkering and soon came up with a very early galvanometer known as the Schweigger...

A self-educated man with a brilliant mind, Michael Faraday was born in a hardscrabble neighborhood in London. Through the combination of insatiable curiosity and a powerful will to succeed, he transcended his austere beginnings to...
