Consider a solenoid of length 0.2 m, having 399 loops. The equation for the magnetic field of a solenoid is given as $$B_{solenoid} = \mu_0 I \frac{N}{L}$$, where $$\mu_0 = 4\pi \times 10^{-7} \frac{T \cdot m}{A}$$. What current is necessary to produce a 4.7 T magnetic field? (please provide your answer in kA to 2 decimal places)
