Lorentz Force Lab

Apparatus to hold flat neodymium magnets (2 x 1 x 1/16 in.). This creates a moderately uniform magnetic field between the magnets and the whole apparatus can be placed on a scale. Placing a wire segment with a horizontal current flow between the magnets will exert a force proportional to the current according to the Lorentz Force Law (for straight wires):

                               

Force = (current)\*(length of horizontal wire) cross-product (Magnetic Field).
The wire should
