Adjustable Magnetic Field Permanent Magnet

Overall Dimensions: 320mm(L) x 200mm(W) x 493mm(H)
Pole face diameter: 100mm

Air gap range: 10-100mm

Weight: 86kg

Permanent magnets have very favorable conditions for generating a constant magnetic field, but their single structure limits their application to a certain extent. Our company is committed to developing various adjustable magnetic field permanent magnets, so that the air gap can be adjusted, the magnetic field strength can be adjusted, and the area is uniform and stable. The function of the permanent magnet is closer to that of an electromagnet, and it can be used more widely.

Performance test report

Introduction
1. Test purpose
Through the analysis of the test results, the evaluation of the product performance is obtained; Evaluate whether the test product meets the technical requirements; Provide reference data for product design and after-sales service, and provide a strong basis for leaving the factory.
2. Basic information
Product Name: Adjustable Magnetic Field Permanent Magnet		Product model:	Customized
		Test time:	June 26, 2023
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.
Measurement environment
