Magnetic Fields

"Magnetic Fields" explores the ubiquitous yet often unseen force of magnetism, from the Earth's magnetic field to its pivotal role in modern technology. This book unveils how magnetism, discovered in ancient times, underpins essential technologies like compasses and medical imaging, such as MRI. It emphasizes that understanding magnetism is crucial for navigating and innovating in the 21st century. The book begins by laying a historical foundation and introducing fundamental concepts, gradually building towards more complex theories, including the geodynamo theory and magnetic reversals.

Did you know that Earth's magnetic field not only guides compass needles but also shields our planet from harmful solar radiation? Furthermore, the technology behind magnetic storage and electric motors originates from these same magnetic principles.

Progressing methodically, "Magnetic Fields" covers the basic principles, explores Earth's magnetic field, explains the workings of a compass, and dissects the technological applications of magnets in electromagnetism, magnetic storage, electric motors, and generators. It concludes with cutting-edge research like magnetic levitation, offering a unique perspective by integrating theoretical explanations with practical applications.
