The Electric and Magnetic Personalities of Mr. Maxwell
Maxwell's equations are used in nearly all engineering marvels, including computers, cell phones, TVs and solar cells.Copyright NIDA for Teens http://teens.drugabuse.gov/blog/tag/twitter/
Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through multiple topics and activities, students see how electricity and magnetism are interrelated.
Throughout history, the subject of electricity and magnetism has been a topic of interest for physicists and engineers. Great minds such as Faraday, Gauss and Maxwell made discoveries that continue to shape the world in which we live. In particular, Maxwell's equations are used in nearly all engineering endeavors. For example, any time a person uses a TV, computer, cell phone or solar energy, Maxwell's equations are involved. This lesson's associated activities are prime examples of how Maxwell's equations are used for engineering purposes for the improvement and functioning of our daily lives. Electricity and magnetism pervasively affect modern industries such as communication, entertainment, medicine, defense and manufacturing.
After this lesson, students should be able to:
- Explain the interconnections that exist between electricity and magnetism.
- Describe how a changing magnetic field produces current in a loop of wire.
- Determine the factors that affect the strength of electromagnetic forces.
