1) Imagine a copper rod hanging from the ceiling (of mass M and length Lo and resistance R) that is suspended by two springs with effective spring constant k and unstretched length Li. Initially there is no magnetic field or current flowing through the wire. a. How much is the spring initially stretched due to the hanging mass? After 3 seconds, the magnetic field reaches a maximum and starts declining as B(t)=9-3t. e. What is the magnitude and direction of the induced current at this point? f. What is the direction and magnitude of the Lorentz force on the copper rod?
