Electromagnetic Interference and Electromagnetic Compatibility (EMI/EMC) first became a concern during the 1940s and 1950s, mostly as motor noise that was conducted over power lines and into sensitive equipment. During this period, and through the 1960s, EMI/EMC was primarily of interest to the military to ensure electromagnetic compatibility. In a few notable accidents, radar emissions caused inadvertent weapons release, or EMI caused navigation systems failure, and so military EMI/EMC was concerned chiefly with electromagnetic compatibility, especially within a weapons system, such as a plane or ship.
