Why does the electric pen light up when testing the inner pot of the Xiaomi Multifunctional Rice Cooker 4L, but there's no sensation when touching the inner pot with hands? Is this a leakage?

This voltage belongs to induced electricity and does not cause any harm to the human body. Please free feel to use it.
1. When the rice cooker is powered on, the metal shell will have an induced electric field. Therefore, the product is equipped with an earth wire that will discharge to the ground. If the earth wire of the socket is damaged, the metal shell of the rice cooker will have a small amount of induced electricity residue, but this is not harmful to the human body;
2. The product is a Class I appliance and is equipped with grounding protection. The rice cooker needs to be used on a socket with a good earth wire;
3. Earth wire is a method of electrical protection, which is used to quickly introduce current to the ground through the earth wire when the appliance leaks electricity or has induced electricity, thereby making the appliance no longer electrified and ensuring usage safety.
Please refer to the instructions for leakage and induced current:
1. A leakage is caused by damage to the AC part of the device, which leads to the device's shell becoming electrified and can harm the human body;
2. An induced electric field is generated by the interaction between the device's electromagnetic field and the metal shell. Since the induced electric field does not form a circuit, it will not discharge to the human body.
