Problem 27.10: Find the mass of the current carrying rod in a magnetic field

Please wait for the animation to completely load.

The blue rod has a current flowing through it and sits in a uniform external magnetic field that points out of the page (as represented by the gray circles with white dots). The probe at the top records the force required to support the rod (position is given in centimeters, magnetic field is given in tesla, current is given in amperes, and force is given in newtons). Restart.

  1. In which direction does the current flow through the rod?
  2. What is the mass of the rod?
