An electromagnet is made by inserting a soft iron core into a solenoid. The solenoid has 1800 turns, radius 2.00 cm, and length 16.6 cm. When 2.00 A of current flows through the solenoid, the magnetic field inside the iron core has magnitude 0.620 T. What is the relative permeability KB of the iron core?
