Hammer Balance

  • Hammer balances in a manner that appears impossible, but does so because 1) center of mass is┬ánot beyond edge of table, and 2) angular displacement of hammer increases potential energy of system, meaning system is stable. Stick end can be pushed very close to table edge, as seen in above photo.
  • Demo located in L02, section B4

  • Purpose: Demonstrate how the magnetic force on a current
    carrying wire depends on the angle between the current and the external
    B-field.
