Read the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde. It was late in the afternoon, when Mr. Utterson found his way to Dr. Jekyll’s door, where he was at once admitted by Poole, and carried down by the kitchen offices and across a yard which had once been a garden, to the building which was indifferently known as the laboratory or dissecting rooms.

man vs. nature - first choice

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
