We theoretically propose and experimentally demonstrate an active quasi-static magnetic cloak enabled by a single magnetic dipole. The cloaking effect can be achieved by active cancelation of the background magnetic field using the magnetic dipole. Compared with previous multi-unit designs. the single-unit design drastically reduces the number of control units required. https://www.roneverhart.com/Apple-Watch-Series-6-GPS-Cellular-40mm-Silver-Aluminum-w-White-Sport-Band/
