PHYSICS 489 - Week 23

PHYS 23.1 Applications
Reading: Don't Panic Vol II pp 188-202
Homework: Ch. 10: Pr 5,6; Ex 5,6
Keywords: Review chapter 10

Learning Objectives:

At the end of this session the student will be able to:
  1. distinguish those situations where the Circuital Law is applicable.
  2. solve problems using the appropriate law to find magnetic fields and forces.

PHYS 23.2 Faraday's Law
Reading: Don't Panic Vol II pp 216-223
Homework: Ch. 11: Pr 1-3; Ex 1-3
Keywords: Magnetic flux, Lenz's law, Non-conservative E-fields.

Learning Objectives:

At the end of this session the student will be able to:
  1. analyze experiments demonstrating that induced electric fields are non- conservative by evaluating the left side of Faraday's Law.
  2. calculate the magnetic flux through a specified surface bounded by a conducting wire.
  3. Determine the time rate of this flux, whether the change is due to changing the magnitude or direction of the B-field or by changing the area or orientation of the loop.
  4. use Faraday's Law to determine the emf induced around the loop.
  5. use Lenz's Law to determine the "direction" of the induced emf.
  6. give a concise, clear statement of Lenz's Law.

EXAM 6


PHYS 23.3 Applications of Faraday's Law
Reading: Don't Panic Vol II pp 220-225
Homework: Ch. 11: Pr 4-6; Ex 4-6
Keywords: Mutual inductance, Self inductance, Electric generators

Learning Objectives:

At the end of this session the student will be able to:
  1. calculate induced currents using Faraday's Law to simple situations including moving rods, rotating loops, etc.
  2. verify Lenz's Law by first solving for currents and directions analytically.
  3. define mutual and self-inductance.
  4. outline the procedure for determining the self -inductance of a circuit.
  5. discuss the differences between the conservative electrostatic E-field and the non-conservative induced E-field.
