Question 1 · 1 mark · Difficulty 1/3

Which rule is used to determine the direction of the force on a current-carrying conductor in a magnetic field?

  1. Fleming's left-hand rule
  2. Fleming's right-hand rule
  3. Lenz's law
  4. Faraday's right-hand rule
Show answer & explanation
✓ Answer: AFleming's left-hand rule
Fleming's left-hand rule applies to motors and the motor effect, where the thumb points in the direction of motion (force), the index finger in the direction of the magnetic field, and the middle finger in the direction of conventional current. Fleming's right-hand rule is used for generators, not motors.
Question 2 · 1 mark · Difficulty 2/3

A straight conductor carries a current of 4 A and sits in a uniform magnetic field of flux density 0.05 T. The length of conductor in the field is 0.3 m and it is perpendicular to the field. What is the force on the conductor?

  1. 0.06 N
  2. 0.60 N
  3. 0.012 N
  4. 6.00 N
Show answer & explanation
✓ Answer: A0.06 N
Using F = BIL: F = 0.05 × 4 × 0.3 = 0.06 N. A common error is to multiply only two of the three quantities or to misplace the decimal point.

AQA GCSE Physics: Electric motors and loudspeakers FAQ

How many AQA GCSE Physics questions on Electric motors and loudspeakers are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Electric motors and loudspeakers for AQA GCSE Physics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real AQA paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for AQA GCSE students preparing for Physics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Electric motors and loudspeakers practice with other Physics topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Electric motors and loudspeakers questions aligned to the official AQA GCSE Physics syllabus?
Every question is written against the published AQA GCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Electric motors and loudspeakers typically tested on AQA GCSE Physics papers?
Electric motors and loudspeakers appears across multiple question types on real AQA GCSE Physics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
