PROBLEM TO BE SOLVED: To provide a magnetic processing system, and a magnetism control device capable of reducing deviation of magnetization when the demagnetization current is less. SOLUTION: A magnetism control unit (a magnetism control device) 6 comprises a divider 24 for calculating the inductance of a demagnetization coil by dividing the magnetic flux side measurement value detected by a magnetic field detector by the measurement value of the demagnetization current, a conversion means 18 for calculating the current command value of the demagnetization current by dividing the preset magnetic flux command value by the calculated inductance, and learning control means 19 to 25 for correcting the current command value by using the measurement values of the magnetic flux in the past and the current command variables in the past by changing the value of the current command variable to the current command value.
