Introduction Magnetism is one of the fundamental forces of nature, and it arises from the motion of electric charges. The magnetic force on moving charges is a cornerstone of electromagnetism, bridging the concepts of electric current, magnetic fields, and particle motion. Understanding this phenomenon is crucial in fields ranging from particle physics and electrical engineering…

Earth is not just a rotating sphere of rock and water; it is also a giant magnet generating a magnetic field that extends from the planet’s interior out into space. This field, known as geomagnetism, plays a vital role in navigation, protects life from harmful solar radiation, and influences atmospheric and geological processes. Understanding Earth’s…

Introduction Magnetism is a fundamental aspect of nature that has fascinated scientists for centuries. From the first observations of natural magnets in ancient Greece to modern applications in electrical engineering, electronics, and medical imaging, magnetism plays a critical role in technology and daily life. Central to the understanding of magnetism are magnetic fields and magnetic…

Magnetism is the force exerted by magnets when they attract or repel each other or other materials. Historically, lodestones were the first naturally occurring magnets discovered thousands of years ago. William Gilbert, in the 16th century, studied magnetism systematically and recognized Earth as a giant magnet. Types of Magnets Magnetic Poles 2. Magnetic Fields and…
