Distinguish North And South Poles Of NdFeB Magnets

We have three method to distinguish north and south poles of NdFeB magnets. The first one is determine by the geographic pole. If it is a bar magnet, you can use a line tied the middle position of NdFeB magnet,then take it hanging up. The end pointing north is north pole, and the contrary end is south pole. Certainly you can judge by the principle of attraction repulsion. Put one end of magnet close to the south of known magnet, if they can suck together, it must be north pole. The last method is most simple. Put one end of the magnet close to north pole of stable compass. If they are repulsion, the end must be north pole.

As we all known, the mineral content in the water are different with geographical environment. Hazardous substances in the water has great effect on our life and health. Calcium salt and magnesium salt in the water are all insoluble. It will effect animal absorption and plants photosynthesis. High strength NdFeB magnetized can change the surface tension solubility, density and other physical properties of water.

Drinking magnetized water can keep healthy and condition human body microcirculation system, digestive system, endocrine system and nervous function. It also could improve human immunity, prevention and treatment various diseases.
