Reference no: EM132094983

Question: It is desired to construct a solenoid that will have a resistance of 4.00 O (at 20°C) and produce a magnetic field of 4.00 ? 10-2 T at its center when it carries a current of 3.25 A. The solenoid is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenoid is to be 1.00 cm, determine the following. (The resistivity of copper at 20°C is 1.7 ? 10-8 O · m.)

(a) the number of turns of wire needed to build the solenoid ______ turns

(b) the length the solenoid should have ______ cm
