Discussion Overview

The discussion revolves around finding a comparable textbook to "Electricity and Magnetism" by E. Purcell & D. Morin, specifically one that is available for free online and suitable for introductory electricity and magnetism courses. The conversation touches on the depth and mathematical rigor of the original text.

Discussion Character

  • Debate/contested

Main Points Raised

  • Post 1 describes Purcell's textbook as deep and requiring strong knowledge in advanced mathematics and physics, particularly highlighting concepts like magnetic force as a result of relative movement and the use of vector potential for calculating magnetic fields.
  • Post 2 suggests "Introduction to Electrodynamics" by Griffiths as a potential alternative, though it is noted that this book is aimed at juniors and seniors.
  • Post 3 questions the availability of a textbook that matches Purcell's rigor but is suitable for freshman/sophomore students.
  • Post 4 expresses doubt about finding a textbook as rigorous as Purcell's for the specified level, asserting that Purcell is the best option available.

Areas of Agreement / Disagreement

Participants express differing opinions on the availability of comparable textbooks. While some suggest alternatives, there is a consensus that finding a textbook as rigorous as Purcell's for lower-level students is challenging.

Contextual Notes

The discussion highlights the specific audience and level of rigor desired, indicating a potential gap in available resources for introductory courses that maintain a high level of mathematical and conceptual depth.

Please help me find a similar textbook to the one below. Note that I'd like it on the internet and free. Thanks!

"Electricity and Magnetism", E. Purcell & D. Morin, 3rd edition. From what I've heard, it's a textbook for an introductory electricity and magnetism class. Note that it has some advanced 3D calculus in there. Here's a description of it:

Text from a Nobel Laureate. What a privilege that we own to be able to not only read it but to study seriously from it.

First of all, this book is deep. You need to be very potent in advanced Maths (Vector analysis) & Physics (Special Relativity) to be able to discover the beauty of EM theory that Purcell presents in this remarkable book.

This book tells you that:

1. Magnetic force is actually electric force caused by relative movement of charged particles. (You need to learn Special Relativity before you can understand Chap 5)

2. How to calculate magnetic field using vector potential( just in a similar way that we use to calculate electric field using scalar potential). If you want to know how to derive Biot Savart Law, which Halliday's Physics won't even bother, you will find it in Chap 6.

3. Both integral and differential form of Maxwell equations (in terms of vector operators, e.g. G.D.C.-- Gradient, Divergence and Curl)

Hey there,

Some people love the book: "Introduction to electrodynamics", by Griffiths. Check it out and see if it's your cup of tea.

Ok, but it says this book is for juniors and seniors taking intermediate level e&m. Is there any textbook as rigorous as the one I mentioned and is for freshman/sophomore level e&m?

I'm afraid there isn't. Purcell is the best book in this regard.
