QUESTION 1 https://per.physics.illinois.edu/per/IE/ie.pl?phys112/ie/08/IE_movingcoil X X X X XX X W X X X X XX X X X X X X X X X X X X X X X Lg At t=0, a rectangular coil of resistance R = 2 ohms and dimensions w = 3 cm and L = 8 cm enters a region of constant magnetic field B = 1.6 T directed into the screen as shown. The length of the region containing the magnetic field is LB = 15 cm. The coil is observed to move at constant vėlocity v = 5 cm/s. What is the force required at time t = 0.8 sec to maintain this velocity? Answer in uN (u = micro = EE-06)

In the figure (Figure 1) the top wire is 1.1 −mm−mm -diameter copper wire and is suspended in air due to the two magnetic forces from the bottom two wires. The current flow through the two bottom wires is 75 AA in each. Calculate the required current flow in the suspended wire. Express your answer using two significant figures. ICu=____________A
