A magnetic therapy device has been disclosed. In one embodiment of the magnetic therapy device, the device is disk-shaped, four inches in diameter, and ¾inches thick. A disk with ten neodymium magnets mounted on the disk is mounted on a motor. The motor spins the disk, creating a dynamic magnetic field that may be useful for healing human tissue. The motor is powered by a rechargeable battery, which in turn is recharged via an inductive coil. The inductive recharging system allows the device to be completely sealed with no electrical contacts, making it safe to use near water. This embodiment also has a sequential controller which causes the device to become active for thirty minutes and then become inactive, and uses a tri-state LED to indicate the status of the device.
