force on loop

Hall Effect charges in current are forced to One Side of a (flat) wire due to FB. measure voltage due to this force correlate the V with the B

Hall Voltage determines the sign of the net charge motion. Positive carriers Negative carriers

Size of B effects Voltage Observed (Stasis) d = width = w v = vd = drift velocity This is called the “Hall Voltage” VH.

Carrier Density (n) and Hall Voltage Equations Recall that n = #carriers per unit volume and that
