Exploring Magnetism

Here's a posting of some of the ways to see what the local magnetic field is doing. For some really cool magnets and materials to design your own experiments check out:

This magnet is floating in a field created by the device shown below. By measuring It's movement, changes in the local magnetic field can be observed.

This device was purchased from K&J Magnetics. Other than making a pretty cool desktop ornament, it demonstrates some very interesting properties of magnets and different magnetically affected materials.

This is just one of several recorded anomalies as described in the discussion on the Home page of this blog "Anomalies In The Earth's Magnetic Field" (Click To Enlarge)
