Magnetism is a fundamental physical phenomenon describing the force exerted between magnetic poles, which can manifest as either attraction or repulsion. This force originates from the movement of electric charges and is mathematically unified with electric fields in the concept of electromagnetism. Magnetic fields can be generated by various means, including steady electric currents flowing through conductive materials. These principles are harnessed in countless technologies, ranging from large-scale power generation via transformers and motors to precise medical diagnostic imaging. The study of magnetism remains crucial for advancing scientific understanding and developing advanced technological applications across multiple fields of physical science.
