PT 3: Arrays of supermagnets: Bar magnet and compass
The field is zero around a blob of small neodymium magnets ...unless you align them first! Color CRTs get distorted! Make some rotating compasses from rings of magnet beads. (Sell them at weekend flea markets!) These are 8mm and nickel plated. For various suppliers links, see bottom of http://amasci.com/spheres/ These are around $0.35 each if bought in qty. from Mr. George, http://www.supermagnetman.net/...
