Weight's effect on a current balance loop

  1. May 13, 2012 #1
    The problem is an experiment has been conducted where a solenoid current loop is matched to a current balance loop; the experiment was to determine the relationship between the current though the solenoid and the uniform magnetic field produced in the solenoid.

    one element of the experiment was to place a small staple on the end of a wire. The question i am stuck on is that i have to explain how you can use the weight of the staple on the current balance to determine the magnetic field in the solenoid (Relate Back to the aim).

    this was a question i have in my homework and the only other information we were given was the following results:

    Solenoid Loop Current (Amps)................................Current Balance Loop Current (Amps)
    3.0...................................................................0.8
    2.5...................................................................0.9
    2.0...................................................................1.1
    1.5...................................................................1.5
    1.0...................................................................2.2
    0.8...................................................................3.0
