Abstract: An apparatus for stabilizing currents is provided to obtain a precise current by using a magnetic field which is varied in a coil according to the variation of the currents. An apparatus for stabilizing currents includes a solenoid coil(16), a magnetic field sensor(11), a PID(Proportional Integral Derivative) controller(14), and a current controller(15). The solenoid coil is series-connected to a current source to supply currents to a load. The magnetic field sensor installed in the solenoid coil measures variation amount of the magnetic field according to current variation of the current source. The PID controller outputs a compensation signal for adjusting currents according to the variation amount of the magnetic field, which is measured by the magnetic field sensor. The current controller precisely adjusts the intensity of current, which is supplied from the current source to the load, according to the compensation signal received from the PID controller.

Abstract: PURPOSE: An apparatus for measuring a thermal expansion coefficient of a non-magnetic member is provided to precisely measure the thermal expansion coefficient of the non-magnetic member while storing the non-magnetic member in a normal state. CONSTITUTION: An apparatus for measuring a thermal expansion coefficient of a non-magnetic member(2000) includes a coil(100) wound around the non-magnetic member(2000) by a predetermined number and expanded physically. A power supply unit(200) applies current having different polarities to both ends of the coil(100). An electronic thermometer(400) detects a temperature variation of the non-magnetic member(2000). A magnetometer(500) detects a magnetic field variation according to the expansion of the coil(100). A controller(700) is connected to the electronic thermometer(400) and the magnetometer(500).
