climax

after following, but not really , the young hunter on his search for the heron, sylvia slips out of bed alone in the middle of the night to find the heron for herself. perched at the top of a gigantic pine tree, sylvia spots the heron, and its nest, in a dead hemlock tree across the way. the following morning she returns home to find her grandmother and the hunter waiting for her at the door. in the moment when she plans to tell the hunter where to find the heron, she suddenly decides to protect the heron and remain silent; even the promise of much needed money does not sway her.

explanation:

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.
