Abstract
A metallic ball has a sliding sleeve, a shell, at least one magnet and a mounting bracket. The sliding sleeve has an open upper end, an open lower end and an outer surface. The shell is spherical, is mounted securely around the sliding sleeve between the open upper end and the open lower end of the sliding sleeve and has a reinforcing disk mounted around the outer surface of the sliding sleeve and has a top surface and may have a protruding portion. The magnet is on the top surface of the reinforcing disk. The mounting bracket is mounted around the sliding sleeve and on the top surface of the reinforcing disk to cover the magnet and has a wall extending toward and engaging the reinforcing disk and completely covering the magnet to effectively avoid the magnet being broken or damaged.
