Magnetic fasteners are devices that use magnets to securely hold two objects together. They are commonly found in various applications, such as clothing, bags, and electronic devices. These fasteners provide a convenient way to open and close items without the need for traditional buttons or zippers. The main advantage of magnetic fasteners is their ease of use. They allow for quick access while still providing a strong hold. Additionally, they can be designed to be aesthetically pleasing, making them a popular choice in fashion and product design. Examples include magnetic snaps and magnetic clasps.
