1. Magnetic tool pendant: magnetic tool pendant can be used to hang iron objects, such as key ring.
2. Magnetic buckle of handbag: generally, the opening of the handbag will be equipped with a magnetic buckle, which can be opened and closed easily and can also prevent theft.
3. Magnetic stripe of refrigerator door: The magnetic stripe installed on the refrigerator door can closely connect the refrigerator door and the refrigerator body, achieving good refrigeration effect.
4. Compass: hang the midpoint of the bar magnet with a thin line. When it is stationary, its two ends will respectively point to the south and north of the earth. The end pointing to the north is called the north pole or N pole, and the end pointing to the south is called the guide pole or S pole.
5. Magnetic stationery box: A stationery box is a box used by students to hold pens, pencils, rulers, erasers and other stationery. There are many kinds of texture, generally including wood, iron, plastic and other products with different shapes, most of which are rectangular.
6. Magnetic blackboard: The magnetic blackboard is generally made of wood or frosted glass, lined with magnetic strips inside the blackboard, or attached with magnetic particles on the surface.
7. Magnetic badge: When using, please take off the magnet at the back and place it on the inside of the clothes. At the same time, place the card face on the outside of the clothes to make it naturally attract.
8. Water inlet and outlet valve of full-automatic washing machine: the water inlet system of full-automatic washing machine adopts water level pressure switch and the water inlet valve is adjusted by the program controller. It can let foam and sewage in the washing liquid overflow during rinsing.
9. Inductive flush valve in the toilet: infrared ray induction receives the human body signal well, transfers the extremely weak signal to the relay, the relay starts the electromagnetic valve, the valve opens, and the water flows out.
