Rod magnets are just taller brothers of the disc magnets. Just ideal to hold things up!
All rod magnets in the above list are neodymium and have a galvanized or nickel-plated coating to prevent corrosion.
Rod magnets can be used on a magnetic board. Because of the nickel-plated coating they gleam, as it were. Thanks to their high pulling power, postcards, birthday cards, and shopping lists can be hung on a whiteboard or magnetic board.
Moreover, rod magnets are easier to handle than disc magnets. Because of their height you can release them faster from the board.
