Force on a Conductor F=BIl - AQA GCSE Physics Calculation Practice Book

F = BIl is often the last equation students encounter before the exam, meaning they get the least practice with it. This AQA GCSE Triple Physics workbook makes sure it is not a blind spot, with 12 scaffolded questions using the EVERY method framework.

The EVERY method breaks each calculation into clear steps: Equation, Values, Enter values into the equation, Rearrange if needed, Your units. Every question has a structured EVERY table for students to complete, building a consistent problem-solving habit. Questions get progressively harder: Q1-3 are straightforward, Q4-6 introduce unit conversions, and Q7-12 require rearranging the formula.

What's inside:

- 12 progressive questions on Force on a Conductor (F = B x I x l)

- Structured EVERY method table on every question page

- Progressive difficulty: simple substitution, then unit conversions, then rearranging

- Self-assessment tracker with "What made me stuck?" reflection checklist

- Full worked answers for all 12 questions using the EVERY method steps

AQA specification reference: 6.7 Magnetism and Electromagnetism (Triple Physics only, higher tier)

Force on a conductor calculations require students to multiply magnetic flux density, current, and length of wire in the field. Contexts include simple motors, loudspeakers, and electromagnetic devices. Students rearrange for any of the three variables.

Common student mistakes this workbook addresses: confusing magnetic flux density (B, in tesla) with magnetic field strength, using total length of wire instead of the length inside the magnetic field, not converting cm to m for length, and forgetting the unit of force (N).

Suitable for AQA GCSE Physics (Triple only, higher tier).
