Once during a heavy snowstorm, her bus got stuck in a drift coming home. He stared at the empty doorway for a full minute, trying to figure out just what had happened. Surely she would think she was still showing Mr. It was as close to tragic as I ever hope to come.

No part of this book may be used or reproduced in any manner whatsoever without written permission, with the following exception: homework solutions may be copied for classroom use.

To make this manual easier to use, it has been made self-contained. Both the original problem statement and the problem solution are given for each problem in the book. This structure should make it easier to copy pages from the manual for posting after problems have been assigned. Many of the problems in Chapters 2, 5, 6, and 9 require that a student read one or more values from a magnetization curve.

The required curves are given within the textbook, but they are shown with relatively few vertical and horizontal lines so that they will not appear too cluttered. Electronic copies of the corresponding open- circuit characteristics, short-circuit characteristics, and magnetization curves as also supplied with the book.

Students can use these files for electronic solutions to homework problems. Please note that the file extent of the magnetization curves and open-circuit characteristics have changed in this edition. Unfortunately, after the book was published, Microsoft appropriated that extent for a new Access table type in Office That made it hard for users to examine and modify the data in the files.

In this edition, all magnetization curves, open-circuit characteristics, short-circuit characteristics, etc. I have attached corrected pages showing each discrepancy in Appendix D of this manual. Please print these pages and distribute them to your students before assigning homework problems.

If you locate errors which you would like to see corrected, please feel free to contact me at the address shown below, or at my email address schapman tpgi. I greatly appreciate your input! If that feature would be useful to you, please provide me with feedback about which problems that you actually use, and the areas where you would like to have additional exercises.

Thank you. Stephen J. What is the shaft speed in radians per second? Express that speed in both radians per second and revolutions per minute. A force of 5 N is applied to a cylinder, as shown in Figure P What are the magnitude and direction of the torque produced on the cylinder? In horsepower? A ferromagnetic core is shown in Figure P The depth of the core is 5 cm.

The other dimensions of the core are as shown in the figure. Find the value of the current that will produce a flux of 0. With this current, what is the flux density at the top of the core?

What is the flux density at the right side of the core? Assume that the relative permeability of the core is The top and bottom form one region, the left side forms a second region, and the right side forms a third region. The reluctances of these regions are: l l 0. A ferromagnetic core with a relative permeability of is shown in Figure P The dimensions are as shown in the diagram, and the depth of the core is 7 cm.

The air gaps on the left and right sides of the core are 0. Because of fringing effects, the effective area of the air gaps is 5 percent larger than their physical size. If there are turns in the coil wrapped around the center leg of the core and if the current in the coil is 1. What is the flux density in each air gap? Let R1 be the reluctance of the left-hand portion of the core, R2 be the reluctance of the left-hand air gap, R3 be the reluctance of the right-hand portion of the core, R4 be the reluctance of the right-hand air gap, and R5 be the reluctance of the center leg of the core.

A two-legged core is shown in Figure P The winding on the left leg of the core N1 has turns, and the winding on the right N2 has turns. The coils are wound in the directions shown in the figure. A core with three legs is shown in Figure P Its depth is 5 cm, and there are turns on the leftmost leg. The relative permeability of the core can be assumed to be and constant. What flux exists in each of the three legs of the core? What is the flux density in each of the legs?

Let R1 be the reluctance of the left-hand portion of the core, R2 be the reluctance of the center leg of the core, R3 be the reluctance of the center air gap, and R4 be the reluctance of the right-hand portion of the core.

R4 A wire is shown in Figure P which is carrying 5. Calculate the magnitude and direction of the force induced on the wire. The wire is shown in Figure P is moving in the presence of a magnetic field. With the information given in the figure, determine the magnitude and direction of the induced voltage in the wire.

Repeat Problem for the wire in Figure P The core shown in Figure P is made of a steel whose magnetization curve is shown in Figure P How much flux is produced in the core by the currents specified? What is the relative permeability of this core under these conditions?

Was the assumption in Problem that the relative permeability was equal to a good assumption for these conditions? Is it a good assumption in general? It is not very good in general. Its depth is 8 cm, and there are turns on the center leg. The remaining dimensions are shown in the figure. The core is composed of a steel having the magnetization curve shown in Figure c. Answer the following questions about this core: a What current is required to produce a flux density of 0.

Is it twice the current in part a? Similarly, the magnetizing intensity H required to produce a flux density of 0. Similarly, the magnetizing intensity H required to produce a flux density of 1. A two-legged magnetic core with an air gap is shown in Figure P The depth of the core is 5 cm, the length of the air gap in the core is 0. The magnetization curve of the core material is shown in Figure P Assume a 5 percent increase in effective air-gap area to account for fringing.

How much current is required to produce an air-gap flux density of 0. What are the flux densities of the four sides of the core at that current? What is the total flux present in the air gap? A transformer core with an effective mean path length of 10 in has a turn coil wrapped around one leg. Its cross-sectional area is 0.

If current of 0. What is the flux density? Sketch the voltage present at the terminals of the coil. This voltage will be the same polarity as the direction shown on the core, so it will be positive. Figure P shows the core of a simple dc motor.

The magnetization curve for the metal in this core is given by Figure c and d. Assume that the cross-sectional area of each air gap is 18 cm2 and that the width of each air gap is 0. The effective diameter of the rotor core is 4 cm. Other values could be selected for the flux density in part a , and other numbers of turns could be selected in part c. These other answers are also correct if the proper steps were followed, and if the choices were reasonable.
