1 inch diameter rare earth neodymium magnet is a powerful rare earth magnet made from an alloy of neodymium, iron and boron, this size of neodymium magnet has strong magnetic properties and is widely used for industrial purposes, DIY projects, science experiments, machinery, automation equipment, etc., here is a more comprehensive introduction to 1 inch rare earth neodymium magnets.
1 Inch Diameter Rare Earth Disc Neodymium Magnets

Main characteristics of 1 inch neodymium magnets:
Material: neodymium-iron-boron (NdFeB)
Diameter: 1 inch (approximately 25.4 mm)
Thickness: May vary by application, but common thicknesses are 1/8 inch (3.175 mm) or 1/4 inch (6.35 mm).
Shape: diameter is 1 inch, surface is round but can be cylindrical, annular, countersunk magnet rings (round with countersunk screw holes)
Magnetic strength: Neodymium magnets come in different grades, usually ranging from N35 to N52, with the higher number being the stronger the magnet. Magnets with a diameter of 1 inch produce considerable magnetic force in the higher grades (e.g. N52 N54).
Coating: Common coatings include nickel, zinc, or epoxy, which help protect the magnet from corrosion and mechanical damage.
Pull Force: Tensile force varies by thickness, shape and grade and can range from a few pounds to tens of pounds.

1 inch diameter rare earth neodymium magnets safety precautions:
Neodymium magnets are very strong and will hold together with enough force to cause injury or damage.
Store away from electronic equipment, credit cards and pacemakers as they can interfere with their operation.
Neodymium magnets will lose their magnetic properties if exposed to temperatures above their maximum operating temperature, which is typically around 80°C (176°F) for standard grade neodymium magnets.
