This is desired to construct a solenoid which will encompass a resistance of 5.20 O (at 20.0°C) and generate a magnetic field of around 5.00 x 10-2 T at its center when it carries a current of 3.20 A. The solenoid is to be made from copper wire having a diameter of 0.500 mm.
(i) When the radius of the solenoid is to be 1.00 cm, find out the number of turns of wire required.
(ii) When the radius of the solenoid is to be 1.00 cm, find out the required length of the solenoid.
