A Conducting Rod Is Free to Slide Horizontally on Frictionless

question 52

Multiple Choice

A conducting rod is free to slide horizontally on frictionless rails separated by 2.0 m. At a particular time, the rod is sliding at 3.0 m/s to the right, as shown. There is a uniform magnetic field of magnitude 0.66 mT directed into the page. If the resistance R is 220 mΩ, what is the current in the circuit at this time?

• A) 18 mA
• B) 9.0 mA
• C) 87 μA
• D) 3.0 μA
• E) 4.5 mA
