Magnetic connectors are widely used in daily life. Such as smart wearable watches, bracelets, LED lighting equipment, etc. So how to determine the positive and negative poles of the magnetic connector?
What is a magnetic connector?
Magnetic connector, also known as pogo pin magnetic connector. It is a device that achieves connection and separation through magnetic field interaction. It is convenient, fast, and requires no tools for disassembly, and is widely used in various fields.
Working principle of magnetic connector
The working principle of magnetic connectors is to achieve connection and separation through the interaction between magnets. When two magnets are brought close together, the magnetic field between them creates an attraction, causing them to stick together tightly. On the contrary, when they separate, the magnetic field weakens, the adsorption force disappears, and the joint can be easily separated.
How to determine the positive and negative poles of the magnetic connector?
-
Observe the interface identification
Most magnetic connectors will have logos on the outer packaging or inside, usually represented by symbols such as “+”, “-” or “male” and “female”. Therefore, you first need to check the logo on the interface to understand its positive and negative poles.

Use a multimeter to test
If you can’t find a clear identification, you can use a multimeter to test it. Start by plugging the magnetic connector into your circuit board or other device. Then turn on the multimeter and select the resistance level. At this time, if the pointer deflects, it means that there is current flowing at the interface, which is the live part, that is, the negative pole. If the pointer does not deflect, it means that there is no current flowing at the interface, which is the uncharged part, that is, the positive pole. It should be noted that the equipment must be turned off during the test to avoid electric shock accidents.

Use a magnetic tester
If the above method still cannot determine the positive and negative poles, you can also use a magnetic tester to detect it. Place one end of the magnetic tester close to the interface and the other end to the positive and negative poles respectively for testing. If the magnetic tester shows obvious attraction or repulsion, it means that the two ends of the interface are the positive and negative poles respectively. It should be noted that when using the magnetic tester, ensure that the device is turned off and the operator should wear insulating gloves to prevent electric shock.
