[QUOTE="Bill Melody, post: 105026, member: 9146"] Find a TV repair shop in your area. Call and ask if they have an old color TV degaussing coil. Then ask if you can bring your drone to the shop and have them degauss the drone. It was necessary to degausse the old sets with CRT's. Do not use the magnetic tape eraser. The tape eraser is designed to align all the magnetic particles in one direction. A tape eraser is a just a strong magnet. You have already done that by placing the drone dear a strong magnetic field. A degaussing coil uses AC current in a large coil. Start by turning on the deguassing coil then bring it close to the drone wave it over the top, bottom and sides then pull the coil away 5 to 6 feet holding the coil broadside to the drone then rotate the coil 90 degrees to the drone before turning off the coil.
