🔍 Key Concepts

• Permanent magnet vs. electromagnet construction in meter movements • How a moving-coil meter works compared to moving-iron meters • Which meter types are commonly used in DC measurement vs. AC/DC measurement

💭 Think About

• Think about which movement type typically has a light coil of wire that physically moves inside a magnetic field created by a permanent magnet. • Ask yourself: which of these meter types is famous for being very sensitive and widely used in analog DC meters? • Consider which types (iron-vane and electrodynamometer) rely on magnetic interaction between current-carrying coils and soft iron pieces rather than a built-in permanent magnet with a moving coil.

✅ Before You Answer

• Identify which choice is specifically known as a moving-coil, permanent-magnet movement. • Eliminate options that use iron vanes (these generally involve soft iron pieces magnetized by the current, not a permanent magnet with a moving coil). • Verify which type is commonly used as the basic movement in classic analog DC panel meters.
