It is desired to construct a solenoid that will have a resistance of 4.00 (at 20°C) and produce a magnetic field of 4.00 10-2 T at its center when it carries a current of 4.00 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.
(a) the number of turns of wire needed to build the solenoid
turns
(b) the length the solenoid should have
