A properly insulated, tightly wound, 98 cm solenoid is made from wire that is 0.49 mm in diameter. When steady current flows through the solenoid, a potential difference of 43 V is measured across the solenoid terminals. The field inside the solenoid is measured to be 0.45 mT, and the cross section of the solenoid is 3 cm2.
What is the resistivity of the wire material?
Please explain thoroughly as I am confused. Thank you
