Electromagnetics (CC BY-SA 4.0) is an open textbook intended to serve as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics, and includes:electric and magnetic fields; electromagnetic properties of materials; electromagnetic waves; and devices that operate according to associated electromagnetic principles including resistors,capacitors, inductors, transformers, generators, and transmission lines. This book employs the "transmission lines first" approach, in which transmission lines are introduced using a lumped-element equivalent circuit model fora differential length of transmission line, leading to one-dimensional wave equations for voltage and current. This book is intended for electrical engineering students in the third year of a bachelor of science degree program.

Science for Primary and Early Years is a comprehensive guide to the subject knowledge requirements for the teaching of science in early years settings and primary schools. This second edition consists of activities to help the reader extend their own understanding of science. Part One explores understanding the nature of science, processes of planning, carrying out and evaluating scientific investigations, collecting and using data, hypothesizing, predicting, fair testing, use of correct terminology and understanding health and safety as well as key ideas in science that underpin subject knowledge. Part Two builds on these ideas as it explores in more detail life and living processes, the environment, electricity and magnetism, light, sound and the earth in space. This text is part of the series Developing Subject Knowledge which covers English, Mathematics and Science and provides authoritative distance learning materials on the national requirements for teaching the primary core curriculum, working with the early years and achieving qualified teacher status. It is designed for initial teacher training, experienced practitioner self-study, and will help towards GCSE revision. This is a set book for the Open University Course, 'Ways of Knowing: language, mathematics and science in the early years'.
