Magnetic closures are fastening devices that use magnets to hold two parts together. They are commonly found in various products, such as bags, jewelry, and electronic devices. These closures provide a convenient way to open and close items without the need for traditional clasps or zippers. The design of magnetic closures typically includes a magnet on one side and a metal plate or another magnet on the opposite side. When the two parts come close, the magnetic force pulls them together, creating a secure hold. This technology is appreciated for its ease of use and sleek appearance, making it popular in modern design.
