11 A

Explanation:

The magnetic field inside a solenoid can be calculated by the equation:

B = μ * (N/L) * i

Where B is the magnetic field, μ is the magnetic permeability (which is 1.256x10⁻⁶ T/m. A at vacuum), N is the number os loops, L is the length of the solenoid (2 cm = 0.02 m), and i the current.

4 = 1.256x10⁻⁶ * (5653/0.02) * i

0.355i = 4

i ≅ 11 A
