Study Notes
Physics Overview
- The main goal of physics is to understand the natural world around us.
Historical Development
- During the Scientific Revolution in the 17th century, physics emerged as a unique research endeavor in its own right.
- Physics is perhaps the oldest academic discipline, including its inclusion of astronomy.
Physicists and Interdisciplinary Research
- A scientist who specializes in the field of physics is called a physicist.
- Physics intersects with interdisciplinary areas of research, including biophysics, quantum chemistry, engineering, and computer science.
Eddy Currents
- Eddy currents are also known as Foucault currents.
- Eddy currents flow within conductors in planes perpendicular to the changing magnetic field.
- The magnitude of the current in a given loop is proportional to the rate of change of the magnetic flux.
- When graphed within a piece of metal, eddy currents resemble whirlpools or swirls.
- According to Lenz's law, an eddy current creates a magnetic field that opposes the change in the original magnetic field.
