E & M UNIT 07  Electromagnetism

EM INDUCTION (including Faraday’s Law and Lenz’s Law) 
(A) Students should understand the concept of magnetic flux, so they can: 
(1) Calculate the flux of a uniform magnetic field through a loop of arbitrary orientation. 
(2) Use integration to calculate the flux of a nonuniform magnetic field, whose magnitude is a function of one coordinate, through a rectangular loop perpendicular to the field. 
(B) Students should understand Faraday’s law and Lenz’s law, so they can: 
(1) Recognize situations in which changing flux through a loop will cause an induced emf or current in the loop. 
(2) Calculate the magnitude and direction of the induced emf and current in a loop of wire or a conducting bar when the magnitude of a related quantity such as magnetic field or area of the loop is changing at a constant rate. 
(3) Calculate the magnitude and direction of the induced emf and current in a loop of wire or a conducting bar when the magnitude of a related quantity such as magnetic field or area of the loop is a specified nonlinear function of time. 
(C) Students should be able to analyze the forces that act on induced currents so they can determine the mechanical consequences of those forces.
