🔍 Key Concepts

• Magnetic field lines around current-carrying conductors • How distance between conductors affects magnetic coupling • Effect of angle (parallel vs. right angles) on interaction between fields

💭 Think About

• Compare what happens to mutual influence of magnetic fields when conductors are very close versus far apart. • Think about whether parallel conductors tend to have more ongoing interaction than conductors that cross briefly at right angles. • For each choice, ask: does this arrangement make the conductors’ magnetic fields overlap for a long distance or only for a short point of contact?

✅ Before You Answer

• Identify which options place conductors close together versus far apart. • Identify which options keep conductors parallel versus at right angles. • Select the option that both reduces the length of interaction and increases the separation between conductors.
