Astudent decides they would like to have hands - on experience when it comes to transformers .the student takes an iron core (square shaped )and wraps a wire around one side 10 times and call this side the primary side (so np=10). the student takes another wire and wraps it around the opposite side of the iron core 20 times and calls this the secondary side ( so ns=20) the student then hooks the primary side to a 1.50-v lab battery.
a) if the student then used a voltmeter to measure the voltage on the secondary side what voltage should the student measure .
b) if the student uses an amp-meter to measure 200-ma on the secondary side how much current was entering the primary coil ?

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.
