Physics lab Hall Effect

    In this experiment you will use the Hall Effect to measure the strength of magnetic fields. Which of the following are true statements about the Hall Effect? (Select all that apply.)

    The Hall probe that we will use in this lab is made of a semiconductor. (check- i know this is one)

    The value of the voltage across a Hall probe is proportional to the square of the magnetic field in which the probe has been placed.

    The Hall Effect gives rise to a voltage difference across a conductor, perpendicular to the direction of the current flow in the region of magnetic field.

    The Hall probe works best when you align the direction of the current flowing in the probe and the direction of the magnetic field to be parallel.


    So i tried all 4, 123, 12 &4 but to avail. I read over the lab manual but it doesnt seem to help

    If your lab manual and course text and course notes don't contain the basic information about the Hall effect, there's plenty of information available on the web. You should at least be able to quote the formula for the hall voltage...
