🔍 Key Concepts

• Electromagnetic coupling basics: how torque is transmitted without direct mechanical contact • Role of the field coils versus the armature in creating a magnetic field • What must happen for a magnetic field strong enough to "lock" two parts together

💭 Think About

• Which component actually creates the magnetic field that can pull two metal parts together in an electromagnetic device? • Do speed or physical contact alone create a magnetic lock, or is something else required first? • In a typical motor or clutch, what action "turns on" the magnetism that allows power to be transmitted?

✅ Before You Answer

• Identify which choice directly involves creating or supplying current to a magnetic field. • Eliminate any choices that only change mechanical conditions (like speed or rotation) without changing the magnetic circuit. • Ask: which option would still allow a magnetic lock even if the parts were not already turning fast? That’s the key electrical action.
