This is a lesson I used myself to teach the Magnetic Fields concept of the Fields Unit - A level Physics, AQA specification.

Learning objective: To investigate the relationship between current and magnetic force on a wire, and use experimental results to determine the magnetic flux density of a uniform magnetic field.

By the end of the lesson learners should be able to:

Success criteria:

SC1: Describe how a current-carrying wire placed in a magnetic field experiences a force, and explain this using Newton’s third law and Fleming’s left-hand rule.

SC2: Accurately collect and record data for mass change as a function of current, and convert this into force.

SC3: Use the relationship F=BIL and the measured gradient (kg/A) to calculate the magnetic flux density B.

Contains past paper questions that target this topic, some questions require knowledge from prior lessons. The mark scheme is also included to verify answers.

Powerpoint contains 15 slides and 5 past paper questions.
