🧲 Magnetic Field in Physics: Understanding the Invisible Force 🔍 Introduction A magnetic field is an invisible region around a magnet, electric current, or moving charge where magnetic forces can be observed. It plays a vital role in modern physics, electronics, and technology—from electric motors to MRI scanners. 🧭 What is a Magnetic Field? A magnetic field is a vector field , meaning it has both magnitude and direction. It is represented by magnetic field lines , which show how magnetic force acts in space. Symbol: B SI Unit: Tesla (T) Direction: From North pole to South pole outside the magnet ⚡ Magnetic Field Produced by Electric Current When electric current flows through a conductor, it produces a magnetic field around it. Example: Current-carrying wire Solenoid Electromagnet Direction is determined using the Right-Hand Thumb Rule 👍Key properties: Field inside is strong and uniform Acts like a bar ma...
