HI, I am stuck on a problem for a pinball machine. When a coil (solenoid) is energized does the current spike at first? Then does it level off? Does the current build over time while the current is energized? A theoretical graph would be awsome.

Thanks in advance for sharing your hard earned knowledge:)
