A magnetic core refers to a material, such as iron or steel, that is used to enhance the magnetic properties of an electromagnet or transformer. It provides a path for the magnetic field lines to flow through, increasing the strength and efficiency of the device.
Think of a magnetic core like a highway for cars. Just as highways provide a smooth and efficient route for vehicles to travel on, a magnetic core provides a clear path for magnetic field lines to flow through, allowing them to reach their destination quickly and effectively.
Electromagnet: An electromagnet is a type of magnet that consists of a coil of wire wrapped around an iron core. When an electric current flows through the wire, it creates a magnetic field.
Transformer: A transformer is an electrical device that transfers electrical energy between two or more circuits using electromagnetic induction. It consists of two coils (primary and secondary) wound around a common magnetic core.
Magnetic Field Lines: Magnetic field lines are imaginary lines used to represent the direction and strength of the magnetic field surrounding a magnet or current-carrying conductor. They form closed loops from north pole to south pole outside the magnet and continue inside from south pole to north pole.
