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.
