A clear primer on how direct current machines generate and control magnetic fields, with practical notes for students and engineers.

This edition is designed as a notebook to accompany a course of experimental lectures. It explains core ideas about electric currents, magnetic fields, and how these interact in dynamo electric machines and motors. The text emphasizes practical understanding, with notes where the treatment is expanded for clarity and where a descriptive approach may be preferred for beginners.

What you will experience

Foundations of how currents create magnetic effects and how a solenoid forms a magnetic field.
Discussion of magnetization in soft iron versus steel, and what magnetization curves tell us about saturation.
Introductions to the behavior of motors and dynamos, including arguments about torque, speed, and back electromotive force.
Guidance on observing magnetic fields through simple experiments and interpreting results.

Ideal for readers who want a practical, experiment‑driven look at electromagnetism as it applies to dynamos and electric machinery.
