🔍 Key Concepts

• Magnetic field inside a long solenoid and how it depends on number of turns per unit length (N/L) • Relationship: field strength ∝ current × turns per unit length for an ideal solenoid • Effect of changing total turns, coil length, and turn spacing on turns per unit length

💭 Think About

• If you slightly increase the number of turns but also increase the coil’s length, what happens to the turns per unit length (N/L)? • If you increase the number of turns but compress them so the overall length stays the same, what happens to N/L? • Which of the options, if any, actually changes N/L in a way that reduces the field strength?

✅ Before You Answer

• Write the proportionality: B ∝ (N/L) × I for an ideal solenoid and assume current I is constant • For each choice, decide whether N/L increases, decreases, or stays the same • Check whether any option suggests a situation where field strength decreases or stays the same, based on what happens to N/L
