HÀ W = Value Units Submit Request Answer Provide FeedbackProblem2 Two long solenoids are arranged coaxially (one inside the other, centered on the same axis). Both have length L 1.0m. The inner solenoid has r1 1.6 cm, n1 220 turns per centimeter, and resistance Ri = 10Ω. The outer solenoid has radius r2 = 1.8 cm, n2 = 120 turns per centimeter, and resistance R2 5.3 Ω. Since the length of the solenoids is much longer than their diameter, we can ignore the fringing of the magnetic field at the ends and treat the solenoids as infinitely long when calculating the magnetic fields (i.e., we can assume that the magnetic field inside is uniform along the entire length). (a) If the inner solenoid initially carries a current I 1.5 A that then drops to zero at a steady rate over a time interval Δt-: 25 ms, and if the outer inner solenoid is not connected to any battery, what is the current induced in the outer solenoid during this time interval?

- I'm working on some homework and am stumped with this problem. Help would be great, thanks!Magnetic resonance imaging instruments use very large magnets that consist of many turns of superconducting wire. A typical such magnet has an inductance of 40 HH. When the magnet is initially powered up, the current through it must be increased slowly so as not to "quench" the wires out of their superconducting state. One such magnet is specified to have its current increased from 0 AA to 150 AA over 230 minmin. Part A What constant voltage needs to be applied to yield this rate? Express your answer with the appropriate units.
