75. The solenoid of length L = 30 cm and a diameter D = 5,0 cm made of copper wire turns (ρ = 16 nom • m), stacked side by side in a single layer. Wire diameter d = 0,60 mm. What U potential difference must be applied to the ends of the coil to obtain a magnetic field strength H = 2.0 kA / m at the center? The field near the center of the solenoid considered uniform.
