Electricity and magnetism are fundamental concepts in physics that describe the behavior of electric charges and the interactions between them. Electricity deals with the movement and flow of electric charges, whether they are stationary (static electricity) or in motion (electric current). It involves concepts such as voltage, current, resistance, and circuits. Magnetism, on the other hand, is the property of certain materials to attract or repel other materials. It is caused by the motion of electric charges and is associated with phenomena like magnetic fields and electromagnetic waves. Together, electricity and magnetism form the foundation of electromagnetism, a unified theory explaining their interrelated nature.
