Most magnetic materials can be magnetized to saturation in the same direction, a direction called "magnetization direction" (orientation direction). A magnet that has no orientation direction (also called an isotropic magnet) is much weaker than an oriented magnet (also called an anisotropic magnet).


1. What is the standard “Northern and North Pole” industrial definition?

"Arctic" is defined as the north pole of the earth pointing to the north pole of the earth after the magnet rotates freely. Similarly, the south pole of the magnet also points to the south pole of the earth. How to identify the north pole of the magnet without labeling? Obviously it is impossible to distinguish only by the eyes. You can use the compass to stick to the magnet, and the pointer to the north pole of the Earth points to the south pole of the magnet.

2. How to handle and store magnets safely?

Always be very careful, as the magnets will stick together and may pinch your fingers. When the magnets are attracted to each other, the magnet itself may be damaged by the collision (the corners are knocked off or the cracks are knocked out).

Keep magnets away from items that are easily magnetized, such as floppy disks, credit cards, computer monitors, watches, mobile phones, medical devices, etc.

Keep the magnet away from the pacemaker.

For larger magnets, plastic or cardboard spacers should be placed between each piece to ensure that the magnets can be easily separated.

The magnet should be stored in a dry, constant temperature environment as much as possible.

3. How to make magnetic separation?

Only materials that can be attracted to the magnet can function to block the magnetic field, and the thicker the material, the better the magnetic separation effect.

4. What is the strongest magnet?

At present, the highest performance magnet is a rare earth magnet, and in the rare earth magnet, neodymium iron boron is the most powerful magnet. However, in the environment above 200 degrees Celsius, samarium cobalt is the most powerful magnet.
