A student in Barbados investigates Faraday's Law by moving a bar magnet into a solenoid connected to a galvanometer. She notices the galvanometer needle deflects more when she moves the magnet faster. According to Faraday's Law, the magnitude of the induced e.m.f. depends on the

Q: How do I try a free CXC Physics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Physics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Physics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Physics questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Physics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A student in Barbados investigates Faraday's Law by moving a bar magnet into a solenoid connected to a galvanometer. She notices the galvanometer needle deflects more when she moves the magnet faster. According to Faraday's Law, the magnitude of the induced e.m.f. depends on the

Accepted Answer

rate of change of magnetic flux linkage — Award 1 mark for stating that induced e.m.f. is proportional to the rate of change of magnetic flux linkage. A is incorrect — magnet strength affects flux but e.m.f. depends on how fast flux changes. B is incorrect — resistance affects current, not induced e.m.f. D is incorrect — temperature is not a factor in Faraday's Law.

Answer

temperature of the conductor

Answer

rate of change of magnetic flux linkage

Answer

resistance of the coil

Answer

strength of the magnet only
