What is EMF? A Level Physics

(1)
Here’s a short video I made to explain the difference between EMF and potential difference. Hope you like it! How is EMF different from potential difference? When we talk about EMF, that is the energy converted into electrical energy from a source per unit charge. But potential difference is the energy dissipated by a unit charge when charge carriers go through a component, such as a light bulb.

Here’s a worksheet/handout I give to my physics class when teaching magnetic fields. I’ve also provided a link to a video I created to show how to carry out the experiment for plotting the magnetic field lines around a bar magnet. Enjoy!

Here's a revision mat / knowledge organiser for Magnetism & Electromagnetism. It covers magnetic materials, magnetic fields, electromagnets, left hand rule, right hand rule, and motor effect. Print it out as an A3 or shrink it down to A4 (select scale to A4 when printing). I have included a version of the resource with larger font size. Enjoy!

Stationary wave on a string (harmonics) - A Level Physics (Key stage 5)

(2)
I’ve included a few exam style questions on harmonics and stationary waves on a string. Answers are also included. I’ve also included the link to a video I made to explain stationary waves on a string and the calculation of frequencies (harmonics). Hope you enjoy it and, if you do, feel free to subscribe to VTphysics! Enjoy!
