Simple philosophy is 'slow thinking' to ensure your actions are optimal or, at least, worthwhile. Before your information-consumption autopilot rushes you past that 15-word sentence, I invite you to pause with me for a minute or two to reflect on its meaning and the magnitude of its promise.

Simple philosophy is 'slow thinking' to ensure your actions are optimal or, at least, worthwhile. Before your information-consumption autopilot rushes you past that 15-word sentence, I invite you to pause with me for a minute or two to reflect on its meaning and the magnitude of its promise.

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.
