If your prediction is proven incorrect you should leave out all observations that do not support your prediction or simply change your prediction

-- You make a prediction.

-- Your prediction is proven incorrect. (Somebody somewhere somehow came up with an experiment that produced an observation that can't be debated, disputed, or denied, and it demonstrated that your prediction doesn't hold water.)

--  Your prediction is wrong.  There's no getting around it.  You just have to get over it, and give up on that prediction completely.  If you try to bend and fold facts in order to hold on to that prediction, you're just fooling yourself.

-- The smart thing to do is to learn from the other guy's research, know that your first prediction is incorrect, and use your new knowledge to refine your prediction ... replacing it with a new, different one.

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.
