The solenoid current increases from zero to 3.0 A in time interval Δ t = 15 ms. The direction of the current is shown in the figure. a) What are the magnitude and direction of the magnetic field inside the solenoid at the end of time interval Δ t ? (To show the direction, draw an arrow in the figure.) At the end of Δ t, the current is I = 3 A. The number of turns per unit length of the solenoid is n = 25000 turns/m in SI unit. The magnitude of the magnetic field inside of the solenoid is
