Lab #36.2 Magnetism: Seeing Magnetic Fields

Posted on January 1, 2011 by Arbor Scientific

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 [...]

Electric Currents and Fields

Posted on January 1, 2011 by Merrill Falk

Students will observe that the magnetic field created by a coil of wire is perpendicular to the plane of the coil. They will also see that the field is stronger with more current, and that the field reverses direction when the current reverses.

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.

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.
