Explore a comprehensive 36-minute physics lesson on Faraday's law and Lenz's law. Begin with an introduction to magnetic flux, drawing parallels to electric flux. Discover how magnetic flux depends on magnetic field strength, loop area, and field angle relative to the loop's normal. Learn about induced emf in wire loops due to changing magnetic flux, with Faraday's law determining magnitude and Lenz's law providing direction. Examine examples of flux changes caused by variations in field strength, loop area, and field orientation. Understand Lenz's law's application in determining induced emf and current directions, including challenging scenarios where external flux changes oppose the original flux. Conclude with a study of motional emf as a special application of Faraday's law, deriving potential difference expressions and applying Lenz's law to determine direction in conducting rods moving perpendicular to magnetic fields.
