Choosing a fridge magnet is more than just holding notes. Different materials and types change how magnets work and look. Neodymium and ceramic magnets are strong. Ceramic magnets are cheaper and do not lose their magnetism easily. Neodymium magnets can hold heavy things. Many fridge magnets use ceramic magnets. Safety is important, too. Some magnets are made with eco-friendly materials. You can find magnets made of ceramic, neodymium, and samarium cobalt. There are flat, 3D, photo, and novelty magnets for your fridge.
