A system and device system for controlling a height of a levitated object based on a height selection made by a user. The system includes a user input device configured to receive the height selection made by the user, a base in communication with the user input device, and a power source. The base includes a magnet array having a central electromagnet configured to exert an adjustable magnetic force in a first direction, a plurality of peripheral electromagnets each being configured to exert an adjustable magnetic force in the first direction, and a permanent magnet being configured to exert a non-adjustable magnet force in a second direction at least substantially opposite the first direction. The power source is configured to deliver an adjustable current to the magnet array, such that adjustment of the current controls the levitation height of the object.

An adjustable height golf tee system having a tee and an anchor is discussed. The tee is height-adjustable relative to the anchor. A first anchor includes a cap, a stem, and a tip. The stem can be threaded internally, externally, or a combination thereof. A second anchor includes a base, a first stem, a cap, and a second stem as well as optional spacers. The stems can be threaded internally. Both the first and second anchors can be composed multiple pieces (e.g., a detachable cap, a detachable stem, or a detachable portion thereof) to provide access to an inner cavity of the respective stems.

Apparatuses, systems, and methods are disclosed for an extendable golf tee. An extendable golf tee includes a ball support, a shaft, and extension member coupling the ball support to the shaft, wherein the ball support, the shaft, or a combination thereof are movable along the extension member to set a length of the apparatus from the ball support to an end of the shaft at a predefined length.

A telescoping golf ball tee with an internal locking mechanism is provided. The internal locking mechanism permits the golf ball tee neck to adjust to a desired height while still supporting the weight of a golf ball. Upon impact, a bowl-like member at the base of the golf ball tee neck is forced into a cavity in the golf ball tee base which, in turn, applies force to the golf ball tee neck which prevents the neck from escaping the base.
