2. Basic information
Product Name: Custom Water-Cooled Electromagnet				Product model:		DXFGW2-05
				Test time:		January 7, 2026
3. Testing environment
The detection environment is closer to the actual environmental conditions used by the user, including factors such as lead wire length and ambient temperature. The time is selected in the time interval where the fluctuation of the geomagnetic field is small. Before the test, the instruments required for the test were turned on and warmed up in advance and the measurement environment was recorded, as shown in Table 1.
