A Traveler about to set out on a journey saw his Dog stand at the door stretching himself. He asked [the dog]
sharply: "Why do you stand there gaping? Everything is
ready but you, so come with me instantly." The Dog,
wagging his tail, replied: "O, master! I am quite ready; it
is you for whom I am waiting."
The loiterer often blames delay on his more active friend.

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.
