🔍 Key Concepts

• Magnetic fields around conductors • Difference between voltage (potential) and current (actual flow of charge) • Behavior of capacitors and open circuits in DC

💭 Think About

• Think about whether a magnetic field needs actual movement of electric charges, or just the presence of voltage. • For each choice, ask: Is there a path for charges to move continuously, or is the situation essentially static? • Compare what happens physically around a wire when current is flowing versus when the wire is connected to a battery but the circuit is open.

✅ Before You Answer

• Identify which option clearly involves moving charge (current) rather than just potential or force. • Check if an unconnected DC source can have continuous current flow. • Consider whether a capacitor with only voltage across it has steady current through its dielectric in DC.
