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 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, and in the astronomy resources 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.

A suggestion is to 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!

Research

Hypothesis:

  1. Electromagnetic interactions may be the best project hierarchy.

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
