Visualization of Magnetic Field

  1. Apr 1, 2009 #1
    Suppose I have an electric motor, and I wish to visualize how the magnetic field change by time. Is it possible for me to visualize the magnetic field line without using iron powder or ferrofluid? Is it possible to have multiple hall sensors to detect magnetic field strength in various location near the motor, and then have a computer software to interpret it and convert to 3D model?

    Thanks in advanced.

    It is extremely difficult to measure the magnetic fields inside an electric motor because the gap between the rotor and stator is about 0.1 or 0.2 millimeters. If you try to measure the magnetic field of one without the other, your measurements will have very little meaning.
