Charges/Interactions/Electromagnetics/Quiz

Electromagnetic interaction is a lecture and an article about the application of laboratory physics to the electromagnetic interaction. It is part of a physics initiative to increase and improve resources on Wikiversity. And, it is an offering from the radiation astronomy department to increase awareness of physics in astronomy.

You are free to take this quiz based on the electromagnetic interaction at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links and in the {{radiation astronomy resources}}, {{charge ontology}} and {{physics resources}} templates. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!
