GCSE Physics (9-1) - GCSE Physics - Motor Effect - How to Find Force Direction & Strength (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The motor effect. * How a current-carrying wire experiences a force when placed in a magnetic field. * The interaction between the magnetic field of the wire and the external magnetic field. * The effect of the wire's angle on the size of the force experienced. 2. Fleming's Left-hand Rule. * How to determine the direction of the force on the wire. * Using your thumb for force, first finger for the magnetic field, and second finger for the current. 3. Calculating the strength of the force. * The formula: Force = Magnetic Flux Density x Current x Length (F = BIl). * A worked example demonstrating how to use the formula and convert units. *** EXAM BOARD SPECIFIC INFO *** AQA - Higher tier only IGCSE Edexcel - Everything is relevant to your course!
