Title: Fulfills a need, but needs better proof reading
Review: There is a definite need for a book like this. However, some more careful pre-publishing review would have helped. For example, the permeability of free space is given wrong, consistently, by a factor of 10^20. The formulas for Coulomb's law, and the Biot-Savart law, have the wrong exponent of "r" in the denominator. The formula for inductance of a solenoid implies a dependence of inductance on current, although if the student has the patient to track down the definition of symbols the answer is correct, if expressed in a curious way. All in all, there is a great need for a book like this, but a reference work has to be as far as possible 100% trustworthy and reliable. A second, corrected, version of this book would be invaluable.
