FAQ and answers about magnet

	Q1	Can we buy the magnet?
	A1	Asahi Kasei Microdevices does not sell magnets. For the details on magnets, contact magnet manufacturers. Asahi Kasei Microdevices is willing to help you in designing, especially, selecting the material and shape of the magnet.
	Q2	How should we calculate the magnetic flux density when the shape and material of the magnet are provided?
	A2	For the magnetic flux density calculation sheet, click here.
	Q3	Can we calculate without magnet data including the residual magnetic flux density?
	A3	For the magnet data including the residual magnetic flux density, contact the relevant magnet manufacturer. A rough calculation can be performed using typical data of various magnetic materials on the attached table 1 of the magnetic flux density calculation sheet.
	Q4	What is the difference between the residual magnetic flux density and surface magnetic flux density?
	A4	The residual magnetic flux density is a specific value determined by the magnetic material itself. The surface magnetic flux density indicates the magnetic flux density on the surface when a magnet is manufactured in the actual shape using a certain material. The value necessary for the calculation using the magnetic flux density calculation sheet is the residual magnetic flux density. The value obtained when the distance between the magnet and a measurement point is close to 0 in the magnetic flux density calculation sheet corresponds to the residual magnetic flux density.
	Q5	For the calculation of the magnetic flux density, how can we determine the magnetic flux density at positions other than the center of the magnet?
	A5	Contact us. Asahi Kasei Microdevices is willing to make the calculation for you. Please provide us necessary information such as the material and size of the magnet, the location where you want to know the magnetic flux density.
