Electromagnetic Fields and Energy.pdf
Taken from Preface: The introduction of magnetizable materials deviates from the usual treatment in that we use paired magnetic charges, magnetic dipoles, as the source of magnetization.
The often-used alternative is circulating Amp`erian currents. The magnetic charge approach is based on the Chu formulation of electrodynamics. Chu exploited the symmetry of the equations obtained in this way to facilitate the study of magnetism by
analogy with polarization. As the years went by,it was unavoidable that this approach would be criticized,because the dipole moment of the electron, the main source of ferromagnetism, is associated with the spin of the electron, i.e., seems to be more appropriately pictured by circulating currents.

Taken from Test-Taking Strategies: The questions in the practice test in this book illustrate the types of multiple-choice questions in the test. When you take the test, you will mark your answers on a separate machine-scorable answer sheet. Total testing time is two hours and fifty minutes; there are no separately timed sections. Following are some general test-taking strategies you may want to consider.
* Read the test directions carefully, and work as rapidly as you can without being careless. For each question, choose the best answer from the available options.
* All questions are of equal value; do not waste time pondering individual questions you find extremely difficult or unfamiliar.
* You may want to work through the test quite rapidly, first answering only the questions about which you feel confident, then going back and answering questions that require more thought, and concluding with the most difficult questions if there is time.
* If you decide to change an answer, make sure you completely erase it and fill in the oval corresponding to your desired answer.
* Questions for which you mark no answer or more than one answer are not counted in scoring.
* As a correction for haphazard guessing, onefourth of the number of questions you answer incorrectly is subtracted from the number of questions you answer correctly. It is improbable that mere guessing will improve your score significantly; it may even lower your score. If, however, you are not certain of the correct answer but have some knowledge of the question and are able to eliminate one or more of the answer choices, your chance of getting the right answer is improved, and it may be to your advantage to answer the question.
* Record all answers on your answer sheet. Answers recorded in your test book will not be counted.
* Do not wait until the last five minutes of a testing session to record answers on your answer sheet.
