Javier De Elias Cantalapiedra from Madrid, Spain posted the YouTube video above to show the e/m measurement system that he put together based on the description in our book. His measurement system is based on Hoag’s method, and his nicely laid-out setup allowed him to obtain very nice results (4 to 6% error compared to the theoretical e/m).
Javier is an industrial engineer who works in the telecommunications industry. However, his passion is physics, which he pursues at a (very high) amateur level.
Thank you Javier for sharing!
