Solve the all parts of following question:
Question: It is desired to construct a solenoid that will have a resistance of 5.80 (at 20°C) and produce a magnetic field of 4.00 x 10-2 T at its center when it carries a current of 4.80 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, the resistivity of copper at 20°C is1.7 10-8 Ω m.
Part A: Determine the number of turns of wire needed to build the solenoid turns?
Part B: Determine the length the solenoid should have?
I need help to find the number of turns of wire needed to build the solenoid turns.
