A 40 g horizontal metal bar, 14 cm long, is free to slide up and down between two tall, vertical metal rods that are 14 cm apart
A6.0\times 10^(-2)
T magnetic field is directed perpendicular to the plane of the rods. The bar is raised to near the top of the rods, and a
1.1\Omega
resistor is connected across the two rods at the top. Then the bar is dropped
