Homework Help: Conductor inside an electric motor current calculation

  1. Mar 24, 2012 #1
    1. The problem statement, all variables and given/known data

    A 500 mm conductor inside an electric motor has a force of 1.5 newtons exerted on it. If it is at right angles to a magnetic field of flux density 0.6 T, calculate the current flowing in the conductor.

    2. Relevant equations


    3. The attempt at a solution

    B = 0.6T
    F = 1.5N
    L = 500mm = 0.5m
    I =?

    1.5 = 0.6*I*0.5

    I = 1.5/0.3= 5 amps.
