Apparatus

The apparatus is intended to allow you a great deal of flexibility in what you can do.  Here are some measurements of apparatus components that you may find useful (apologies for imperial units):

• The copper rotor disc has an outer diameter of 4.95″ and inner diameter of 1.02″ and total mass of 962(2) g
• The aluminium rotor shaft has a typical outer diameter of 1.00″ and 0.38″ diameter hole through the center.  The aluminium – without magnets or mounting screws – weighs 283(5) g.
• The four magnets on the rotor shaft weigh 97(1) g each.
• The brass quadrants describe an arc with outer diameter 3.72″ and inner diameter of 1.72″ and mass of 214.5(5) g each.
