Calibrate a hall probe

  1. May 20, 2005 #1
    to calibrate a hall probe, i know we have to generate a known magnetic filed strength (B)...but how??

    Is there an equation relating the "B" with measurable currents, etc???

    Thanks for helping guyz!!

    so do i use a electromagnet (solenoid) n get current thru it to generate a magnetic field???
    but i dun get how i cud know the exact value of B
