Question
- A. Induced potential (HT only): split-ring motor kit AC-output shows (Physics only) (HT only) Describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux.
- B. It says field lines travel from south to north outside the magnet. (coil-core error).
- C. It makes AC and DC equivalent. (compass-response error).
- D. It ignores relative motion or changing magnetic flux. (pole-test error).
Answer
Series Loop df038d selects Induced potential (HT only): split-ring motor kit AC-output shows (Physics only) (HT only) Describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux. as the correct answer.
Explanation
df038d series loop, lamp branch, ammeter reading, switch gap, cell pair, resistor path, symbol check, junction point, closed circuit, wire link. The option "Induced potential (HT only): split-ring motor kit AC-output shows (Physics only) (HT only) Describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux." matches (Physics only) (HT only) Describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field. in Induced potential, transformers and the National Grid (physics only) (HT only). Use the question stem "Which response uses the correct technical wording for this situation? Context: split-ring motor kit AC-output. Learning objective: (Physics only) (HT only) Describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field.. Which answer is most accurate for Induced potential (HT only)?

The wrong options usually swap field direction, current path, source evidence, component role, unit wording or a neighbouring concept. Exam guidance: anchor the choice to the exact phrase in the stem, then explain why the correct option fits that physical process.
Common mistake
National Grid transformer reasoning: avoid AC and DC
Treating AC and DC as interchangeable when answering about National Grid transformer reasoning.
Instead, identify the exact Unit 4.7 idea in Induced potential (HT only), then explain how it links to a bar magnet and plotting compass practical and the objective to describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field.
