## Induced Current

A current can be induced in a conducting loop if it is exposed to a changing magnetic field.

## Inductive Pendulum

Get the swing of electromagnetic induction with this simple tutorial.

## Inductive Reactance

Like resistance, reactance slows an electrical current down. Explained by Lenz's Law, this phenomenon occurs only in AC circuits.

## Lissajous Figures on an Oscilloscope

This tutorial is a three-dimensional simulation of a cathode ray oscilloscope producing Lissajous figures as it compares sinusoidal voltages.

## Magnetic Domains

In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them. See how it works in this tutorial.

## Magnetic Field Around a Wire, I

Whenever current travels through a conductor, a magnetic field is generated.

## Magnetic Field Around a Wire, II

A handful of iron filings helps visualize the invisible magnetic field that circulates around a wire with a current running through it.

## Magnetic Field of a Solenoid

You can create a stronger, more concentrated magnetic field by taking wire and forming it into a coil called a solenoid.

## Magnetic Shunt

Magnetic shunts are often used to adjust the amount of flux in the magnetic circuits found in most electrical motors.

## Mass Spectra

The mass spectrum of a material, deduced using a machine called a mass spectrometer, reveals how many isotopes of a given element are to be found in the material. See here what these spectra look like and how they are useful.
