Magnetic field is set up in a region around a conductor, carrying:

Explanation

When charges are in motion, they have current (AC, DC or pulsating DC); magnetic field is produced around a current carrying conductor due to the flow of these charge.andMagnetic field is created whenever an electric current flows through a conductor. This is because a moving electrical charge creates a magnetic field. The strength and direction of the magnetic field depend on the amount of current flowing and the direction of flow. Magnetic fields can also be created by permanent magnets (bar magnets). These are made from materials that are naturally good conductors of electricity, such as iron. The molecules in these materials line up in rows, which creates a strong magnetic field. When you bring a conductor close to a magnet, the magnetic field from the magnet affects the moving charges in the conductor. This causes current flow, creating a current-carrying conductor, which creates its own magnetic field. These two fields interact with each other, resulting in a force that either attracts or repels the objects.
