Question

A strip of copper 200 mum thick and 4.40 mm wide is placed in a uniform magnetic field of magnitude B = 0.90 T, that is perpendicular to the strip. A current i = 34 A is then sent through the strip such that a Hall potential difference V appears across the width. Calculate V. (The number of charge carriers per unit volume for copper is 8.47 times 10^28 electrons/m^3.) the tolerance is +/-5% By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your instructor.

Explanation / Answer

we know:

n = Bi/Vle

or, V = Bi/nle = (0.90x34)/(8.47x10^28x200x10^-6x1.6x10^-19) = 1.1289x10^-5 Volt

this is the potential difference
