In this video we cover a very important question on a mix of topics , i.e. electromagnetism and also simple harmonic motion and resonance for A level Physics.

This is an Edexcel question but I have selected it so that it's fully applicable to all exam boards, including AQA, OCR A, WJEC, Edexcel, international Edexcel, and similar courses.

Please note this is not an official solution and there may be mistakes and better approaches. I am not affiliated with the exam board and original problem can be found here:
