Successful students will be able to:
- Students should understand the concept of magnetic flux, so they can
- Calculate the flux of a uniform magnetic field through a loop of arbitrary orientation. (IIIE1a1) (Knight 33.3)
- Use integration to calculate the flux of a non-uniform magnetic field, whose magnitude is a function of one coordinate, through a rectangular loop perpendicular to the field. (IIIE1a2) (Knight 33.3)
- Understand Faraday’s law and Lenz’s law, so they can:
- Recognize situations in which changing flux through a loop will cause an induced emf or current in the loop. (IIIE1b1) (Knight 33.4, 33.5)
- Calculate the magnitude and direction of the induced emf and current in a loop of wire or a conducting bar under the following conditions:
- The magnitude of a related quantity such as magnetic field or area of the loop is changing at a constant rate. (IIIE1b2a) (Knight 33.5)
- The magnitude of a related quantity such as magnetic field or area of the loop is a specified non-linear function of time. (IIIE1b2b) (Knight 33.5)
- Analyze the forces that act on induced currents so they can determine the mechanical consequences of those forces. (IIIE1c) (Knight 33.6, 32.7)
- Understand the concept of inductance, so they can:
- Calculate the magnitude and sense of the emf in an inductor through which a specified changing current is flowing. (IIIE2a1) (Knight 33.8)
- Derive and apply the expression for the self-inductance of a long solenoid. (IIIE2a2) (Knight 33.8
- Understand the transient and steady state behavior of DC circuits containing resistors and inductors, so they can:
- Apply Kirchhoff's rules to a simple LR series circuit to obtain a differential equation for the current as a function of time. (IIIE2b1) (Knight 33.10)
- Solve the differential equation obtained above for the current as a function of time through the battery, using separation of variables. (IIIE2b2) (Knight 33.10)
- Calculate the initial transient currents and final steady state currents through any part of a simple series and parallel circuit containing an inductor and one or more resistors. (IIIE2b3) (Knight 33.10)
- Sketch graphs of the current through or voltage across the resistors or inductor in a simple series and parallel circuit. (IIIE2b4) (Knight 33.10)
- Calculate the rate of change of current in the inductor as a function of time. (IIIE2b5) (Knight 33.10)
- Calculate the energy stored in an inductor that has a steady current flowing through it. (IIIE2b6) (Knight 33.8)
- Students should be familiar with Maxwell’s equations so they can associate each equation with its implications. (IIIE3) (Knight 34.4)
