Powerful Magnet Quality Inspection Method

A strong magnet is a special magnet with strong magnetic properties and adsorption power. In order to ensure that the quality and performance of powerful magnets meet standards, strict quality testing is required. The following are several common quality inspection methods for strong magnets:

Magnetic detection: Magnetism is one of the core properties of powerful magnets. By using a magnetometer or magnetic sensor, the magnetic field strength and magnetic field distribution of a magnet can be measured. This can help determine whether the magnet meets specified magnetic requirements. Magnetic adsorption force test: The adsorption force of a powerful magnet is an important indicator of its performance. The adhesion force of a powerful magnet can be measured using a special magnetic tester or scale. The test method can be to directly measure the maximum adsorption force between the magnet and the steel plate, or it can be evaluated by measuring the adsorption force between the magnet and the steel ball.

Appearance inspection: Check the appearance quality of the magnet by visual inspection and touch, including surface flatness, gloss, color and shape, etc. Any surface defects, cracks or foreign matter may affect the performance and longevity of the magnet. Dimensional measurements: It is very important to measure the dimensions and geometric parameters of powerful magnets. Use measuring tools (such as calipers, micrometers) to measure the diameter, height and other dimensional parameters of the magnet to ensure that it meets the specified size requirements. Chemical composition analysis: Powerful magnets are usually made of a variety of metals and alloys. Through chemical composition analysis instruments, the content of various elements in the magnet can be detected to ensure that its chemical composition meets standard requirements. Temperature characteristic test: The performance of powerful magnets may change with changes in temperature. By conducting temperature characteristic testing, the performance of the magnet at different temperatures can be evaluated and its optimal operating temperature range can be determined.
