Purpose
In this activity, students will explore the patterns of magnetic fields around bar magnets in various configurations.
Discussion
A magnetic field is a kind of aura that surrounds magnets. Although it can’t be seen directly, the overall shape of the field can be seen by the effect it has on iron filings.
Required Equipment
3 bar magnets, iron filings [...]

Magnetic Fields around Magnets
Posted on November 9, 2010 by Arbor Scientific
Students will make observations of bar and horseshoe magnets, using iron filings or magnetic chips to map the field. The filings will be close together where the field is strong, and farther apart where it is weak. Lines will form, following the lines of the field, from the north pole to the south.This post was posted in Labs, Electricity & Magnetism and was tagged with iron filings, magnetic fields, magnets, poles

Magnetic Fields Inquiry
Posted on November 9, 2008 by Dr. Russell Harkay
We will explore magnetic field configurations and field strengths for permanent magnets in this inquiry exercise. Students will observe the curved field lines around a permanent magnet, and explore how field strength varies with distance. They will observe the magnetic field created by a current-carrying wire, as well as the current created in a wire when a magnet moves past it.This post was posted in Labs, Electricity & Magnetism and was tagged with magnetic fields, magnets, field lines

Elementary Magnetism: Magnetic Moments
Posted on April 1, 2005 by Chris Chiaverina
A mystery to the ancients and a marvel to Einstein, magnetism is inextricably linked to the operation of motors and generators, the functioning of radio, television and computers, and our understanding of the universe. From the Greeks, who found that certain stones would attract pieces of iron, to Einstein who, as a child, was captivated by the mysterious properties of magnets, humankind's fascination with magnetism has never abated.This post was posted in CoolStuff Newsletters, Energy, Magnetism and was tagged with magnetism, magnets, poles, elementary, electric current
