This is a summary booklet of electromagnetism for high school year 2 physics from the 2023 academic year at Teru-ryokukai. It contains handwritten board notes from the instructor, covering sections §28 to §40. As you can see from the photos, the board notes are by an instructor who teaches at the University of Tokyo's Faculty of Science III, so they are quite easy to understand. There are some annotations as it was used for a comprehensive review of electromagnetism.
