Abstract: A corner bead magnetic bracket has a support portion with at least one magnet embedded therein. The support portion magnetically adheres to a metallic portion embedded in a wall. To increase the magnetic holding power, a washer is placed between the support portion and the magnet. The corner bead magnetic bracket has a shelf portion. To relocate or remove, a user applies enough force to break the magnetic bond and repositions to a new location. Other embodiments include wall and light sconce, vase, curio cabinet, flat shelf, etc. that are easily placed and removed as described above. Rare earth magnets are used to ensure a positive grip.
