🔍 Key Concepts

• Magnetic controller relay operation – how the coil, armature, and spring work together • What happens physically when relay contacts weld or stick together • Difference between causes that affect the coil vs causes that affect the moving parts/contacts

💭 Think About

• Think about what must physically happen inside a relay when the coil voltage is removed for the armature to release. • Which of the listed options would make the armature or contacts stay mechanically stuck, even if the magnetic pull is gone? • Which options relate to electrical conditions that disappear when power is removed, and which relate to permanent mechanical damage?

✅ Before You Answer

• Identify which choices would still have an effect after the coil voltage is removed. • Ask yourself: does this problem sound temporary (only while energized) or permanent (remains after de‑energizing)? • Focus on the option that describes a mechanical sticking or bonding that would prevent the relay from dropping out.
