LEEM-9 Magnetoresistive Sensor & Measuring Earth’s Magnetic Field

Short Description:

As a natural magnetic source, geomagnetic field plays an important role in military, aviation, navigation, industry, medicine, prospecting and other scientific research. This instrument uses a new permalloy magnetoresistance sensor to measure the important parameters of the geomagnetic field. Through experiments, we can master the calibration of the magnetoresistance sensor, the method of measuring the horizontal component and magnetic inclination of the geomagnetic field, and understand an important means and experimental method of measuring the weak magnetic field.
