Induction experiment: Inside the shaded region, there is a magnetic field into the board. – If the loop is stationary, the Lorentz force (on the electrons in the wire) predicts: (a) A Clockwise Current; (b) A Counterclockwise Current; (c) No Current Now the loop is pulled to the right at a velocity v. – The Lorentz force will now give rise to: | GENERAL PHYSICS II Electromagnetism Thermal Physics 3 18 2008 1 CHAPTER XI Electromagnetic Induction 1. Induction experiment - Faraday s and Lenz s laws 2. Induced electromotive force and induced electric fields 3. Mutual inductance and self-inductance 4. Magnetic field energy 3 18 2008 2 In the previous chapter we know that current l magnetic field In this chapter we will study currents produced by changing magentic fields. In other words changing magnetic field l current 3 18 2008
