What does EMI stand for?

Electrical Magnetic Interface
Electromagnetic Interference
Electronic Motion Interference
Electromotive Integration

The correct answer is: Electromagnetic Interference

EMI stands for Electromagnetic Interference. Option A, Electrical Magnetic Interface, is incorrect because it incorrectly combines "electrical" and "magnetic" when the correct term is "electromagnetic". Option C, Electronic Motion Interference, is incorrect because it incorrectly combines "electronic" and "motion" when the correct term involves "electromagnetic" rather than "electronic". Option D, Electromotive Integration, is incorrect because it combines "electromotive" which refers to movement due to electrical currents, with "integration" which does not relate to the acronym EMI.
