A strip 1.2 mm wide is moving at a speed of 25 cm/s through a uniform magnetic field of 5.6 T.What is the maximum Hall voltage across the strip?
A)1.7 mV
B)8.5 mV
C)27 mV
D)1.2 V
E)17 V

The maximum Hall voltage (V_H) can be calculated using the formula V_H = Bvl, where B is the magnetic field strength (in Tesla), v is the velocity of the strip (in meters per second), and l is the width of the strip (in meters). Here, B = 5.6 T, v = 25 cm/s = 0.25 m/s, and l = 1.2 mm = 0.0012 m. Thus, V_H = 5.6 * 0.25 * 0.0012 = 0.00168 V = 1.68 mV, which rounds to 1.7 mV.
