N50 Neodymium Small Disc Magnets 3/16 x 1/16 inch - Round Rare Earth Mini Magnets for Crafts, Closures, Needle Minder, Whiteboard, Miniature Hobby (150 Pack)

A stack of these 3/16 inch neodymium discs disappears inside the spine of a handmade journal — the cover snaps shut with a satisfying click and stays closed without a visible clasp. At N50 grade and 1.5mm thick, they deliver reliable holding through a layer of cardstock or decorative paper while adding no visible bulk to the finished piece.Each magnet is axially magnetized through its thickness, so the holding force acts perpendicular to the face — right for flush-mount closures, fridge and whiteboard mounting, and needle minder assemblies. The NiCuNi triple-layer coating gives a smooth silver finish that won't scratch surfaces, and the nickel layer resists chipping after hundreds of separation cycles. Maximum operating temperature is 80°C (176°F).About the size of a small shirt button and roughly the weight of a paperclip, these magnets are easy to position precisely. Craft makers press one into a decorative button face and set a matching disc on the back of the embroidery hoop — the needle minder grips through the fabric and holds spare needles in place. Costume builders embed a pair inside foam armor panels, securing lightweight pieces flat for easy removal at the end of a long convention day.One lb pull force suits lightweight-to-medium tasks: holding photos and index cards to a fridge, securing journal flaps through two layers of cover stock, or gripping an embroidery needle through hoop fabric. They hold firmly against steel and painted metal; against wood or glass they need a mating magnet or ferromagnetic surface. For hanging tools or supporting significant weight, a larger diameter magnet is the better choice.SAFETY: Strong magnetic field — keep away from pacemakers and electronic devices. If swallowed, magnets can attract across intestinal walls causing serious injury. Keep away from children. Not suitable for anyone under 14.
