Let the permittivity, permeability of free medium, electric field, velocity of light are ε0, μ0, E, c respectively. Thus, the magnetic energy stored in a solenoid is 1 2B2 μ0 ×Al. Was this answer helpful?
1) With a constant and DC power source eventually the solenoid will become fully 'charged'. At that point its 'resistance' term vanishes because it no longer produces an emf against the battery. At this point, the di dt d i d t term will be zero, because the current isn't changing.
You'd have to integrate until t = ∞ t = ∞, aka until the current behaves as if there's no solenoid at all (the integral at the righthand side). Could you please break your answer up into pieces that answer each individual question?
