Problem 28-55a: A solenoid has a length of $30\mathrm{cm}$, a radius of $0.5\mathrm{cm}$, and 375 turns, and carries a $3.5?\mathrm{A}$ current. Find $B$ on the axis at the center of the solenoid. Tries $0/15$ Problem 28-55b: Find the flux through the solenoid, assuming $B$ to be uniform. Tries $0/15$ Problem 28-55c: Find the self-inductance of the solenoid. Tries $0/15$ Problem 28-55d: Find the induced emf in the solenoid when the current changes at $170\mathrm{A}/\mathrm{s}$. Tries $0/15$
