In 1820, Hans Christian Ørsted discovered the relationship between electricity and magnetism in this very simple experiment.

This “magneto-electric machine” was the first to turn motion into electricity.

After discovering the nature of electrical resistance, scientists devised instruments like this one to measure and control it.

The simple voltaic (or galvanic) electrical cell is the most basic type of "wet" cell and demonstrates the fundamental chemistry behind batteries.

Invented around 1930, the Van de Graaff generator is a popular tool for teaching the principles of electrostatics. Others just call it "that thing that makes your hair stand on end." See how it works here.

Italian scientist Alessandro Volta was the first to recognize key principles of electrochemistry, and applied those principles to the creation of the first battery, a simple tool which came to be known as the voltaic pile.

FT-ICR is a powerful type of mass spectrometry, co-invented by the Magnet Lab's Alan Marshall, particularly suited to identifying heavy molecules.

Keith Richards and Eric Clapton owe their fame and fortune (in part) to electromagnetic induction.

In MRI, magnetic fields and radio wave pulses combine to get a unique, and medically beneficial, response from your body's hydrogen atoms. Take a peek in this tutorial.

Mass spectrometers are machines that give scientists a look at the composition and origin of a material by analyzing and quantifying its atoms and molecules. This tutorial shows how a single sector mass spectrometer works.
