A long air-force solenoid having 480 turns, length 32 cm and diameter 3.0 cm carries a current 2.0 A at certain time. The current is rising at a certain time. The current is rising at a rate of 25 A/s. Determine:
i) The self-inductance of the solenoid.
ii) The voltage across the solenoid at that moment.
iii) The magnetic energy store in the solenoid.
