A computer disk drive stores data on a diskette by applying patterns of magnetic charges to the layer of iron oxide on the diskette surface. The disk drive can then
detect these magnetic charges, which can be converted easily to a format understandable by the user. A felt-lined jacket protects the circular diskette from scratches
and smudges. Exposure to which of the following would most likely cause a loss of data stored on a diskette?
DA Astrong magnetic field
B. High humidity
