Abstract: A magnetic moment measuring apparatus is provided to increase measurement precision by measuring magnetic moment of a magnetic body while maintaining the original shape and size of the magnetic body. In a magnetic moment measuring apparatus, a coil(10) has a space for receiving and rotating a magnetic body(20) while keeping the original shape and size of the magnetic body. A power source(Vs) for sending current(I) to the coil is separated from the coil. A resistor(R) is installed between the power source and the coil. A voltmeter(30) measures voltage delivered to the resistor. A magnetic flux sensor(40) is installed in the center of the coil to detect the magnetic flux density of the center of the coil. A magnetic flux density measuring instrument(50) is installed at the outside of the coil and connected with the magnetic flux sensor to measure the magnetic flux density of the center of the coil detected by the magnetic flux sensor. A transfer device(60) has a magnetic body fixer(62) installed in the front end of a non-magnetic rotary rod(61) to fix the magnetic body, inserts the magnetic body by moving the rotary rod to the center of the coil while the power source and the magnetic flux sensor are separated from the coil, and rotates the magnetic body in the front end of the rotary rod at the specific angle in a horizontal direction to the axial direction. A fluxmeter(70) measures magnetic flux generated due to the magnetic body connected with the coil while the power source and the magnetic flux sensor are separated from the coil, and inserted into the center of the coil or due to the magnetic body inserted into the center of the coil and then rotated at the specific angle.

Abstract: PURPOSE: An apparatus for measuring current and power using magnetic field is provided to accurately measure the current supplied to the load side. CONSTITUTION: A housing(110) holds a magnetic field shielding unit(150) which is formed by wrapping a coil(120), a magnetic field sensor(130), a temperature sensor(140), and a pair of coil voltage measuring terminals with an electromagnetic wave shielding agent. The magnetic field shielding unit shields external magnetic field affecting the coil. A measurement controlling unit(160) converts the change of magnetic field inside the coil detected by the magnetic sensor to the current provided to the load side while the current is provided to the load side The measurement controlling unit displays a converted current on a display unit by compensating the current according to the temperature change inside the coil.
