Neodymium rod magnets are cylindrical magnets made from neodymium, iron, and boron (NdFeB). They are known for their strong magnetic properties and are commonly used in various applications due to their high magnetic strength.Neodymium rod magnets are coated with a protective layer (usually nickel, zinc, or epoxy) to prevent corrosion and enhance their durability. neodymium rod magnets are highly sought-after due to their strong magnetic properties, compact size, and versatile applications.
