40mm square ferrite magnet is also called 40mm ceramic square magnet, the specific size is 40mm in length and width, 5mm in thickness. The working temperature is 250℃ better, but it can resist 350℃ highest. There is not coating bescause ceramic magnets are highly resistant to corrosion, oxidation and demagnetization. The square magnet has the same length and width , so is easy to install and do not need to divide length and width.
This 40mm square ferrite magnet can bewidely used in navigator, testing electronic equipment, TV, microwave oven, magnetic therapy equipment, robots, drones and other fields.
