Question 133Electricity & Electronics - QMED

The correct answer is B) notify the electrician or watch engineer of the problem. A loud buzzing noise coming from a magnetic motor controller is typically an indication of a problem, such as a potential electrical issue or a malfunctioning component. The correct response is to notify the appropriate personnel, such as the electrician or watch engineer, so they can investigate the issue and take necessary corrective actions. The other options are incorrect because: A) assuming the motor is operating at full load is not a safe assumption without further investigation, C) assuming the controller is operating normally when there is a clear issue is not recommended, and D) feeling the outside of the casing could be unsafe if the issue is related to electrical problems.
