An investigator needs a uniform 30 mT field, which she intends to produce with a solenoid. She takes a long 10-cm-diameter tube and wraps wire along the length of it, wrapping 1200 turns of wire along a 75-cm length of the tube. How much current must she pass through the wire to produce the desired field?
