Question
Consider the system pictured in the figure below. A = 15.2-cm length of conductor of mass 14.7 g, free to move vertically, is placed between two thin, vertical conductors, and a uniform magnetic field acts perpendicular to the page. When a 5.0-A current is directed as shown in the figure, the horizontal wire moves upward at constant velocity in the presence of gravity. (a) What forces act on the horizontal wire, and under what condition is the wire able to move upward at constant velocity? (b) Find the magnitude and direction of the minimum magnetic field required to move the wire at constant speed. magnitude T
Explanation / Answer
a.) a magnetic field directed out of the page with magnetic force equal to compensate gravitational force
b.)
