This is a basic degaussing circuit, if residual current's requested zero,this circuit usually a switch When necessary the switch is turned off.

Curent-Time Characteristic(Dynamic Characteristic)
Heating element (1) causes the resistance value of Element (2) to increase and make the stable current
extremely small,Thus in many case. The circuit is designed to be linked to the power switch so that degaussing
is perfomed auto matically when the power is turned on.
When excessing power is applied to the themistor,a large current flow momenarily,then the self-heating
feature of the themistor causes the resistance value to increase and the current value to decrease. Thus, the
thermistor controls degaussing function ideally.
