I am working on hall effect based current meter and I run into some troubles running my simulation in LTspice. To be precise I am no sure how to accurately model hall effect sensor. In less accurate models I treated hall effect sensor as voltage source proportional to flux. Now I modelled Hall effect sensor as Wheatstone bridge in order to reflect internal resistance. However not to sure how to relate magnetic flux and change in resistance. I am assuming there is relation between change in resistance and flux as there is definitely relation between change in flux and change in hall voltage. Should I simply apply Ohm’s law?
