A rectangular slice of semiconductor of thickness 2.5 mm carries a current of 150 mA in a magnetic field of 0.5 T.
Deduce what type of material is best suited for a large Hall potential difference, and describe how the magnitude of the magnetic field and the thickness of the material affect the Hall potential difference.
