🔍 Key Concepts

• Effect of magnetic tools on strong permanent magnets and magnetically sensitive components in radar systems • Which radar component relies on a strong magnetic field for operation • Why manufacturers warn about demagnetizing or disturbing magnetic circuits during maintenance

💭 Think About

• Which of these components contains or is closely associated with a powerful magnet or magnetic circuit that could be affected by a magnetic tool? • If a magnetic screwdriver is brought near a strong magnet, what could happen to both the tool and the component’s field alignment? • Which choice is most likely to have its performance changed by even a small disturbance in its magnetic properties?

✅ Before You Answer

• Identify which option is associated with a strong permanent magnet or magnetic focusing system • Rule out components that are primarily electronic signal-processing stages (like low-level or IF/video stages) rather than power-generating devices • Think about safety and manufacturer warnings: which piece usually has a specific caution about avoiding magnetic tools?
