History of Magnetic Field
The history of the magnetic field is very old and as early as the Vedic age people in India know about the magnetic field of the Earth. But the real work in this field began in the late 13th century by French scholars who observed natural magnets with some iron needles and name their endpoints where the magnetic field interacts as the poles.
Then another major breakthrough happens when in 1785 Coulomb verifies that Earth has a magnetic field. After that Hans Christian Oersted a Danish physicist discovered that moving charge produces the magnetic field.
After that in 1831, famous English scientist Faraday demonstrated that a changing magnetic field generates an electric field. This effect came to be known as electromagnetic induction.
Next James Clerk Maxwell was the one who pioneer the field of electromagnetics with Maxwell’s equation which provides a relationship between electric current and magnetism.
Magnetic Field Strength
Magnetic field is defined as the region around a magnet which influences the other magnets. i.e. If we place a test magnet near a powerful magnet it experiences some force due to the powerful magnet the region close to the powerful magnet is called the magnetic field of the magnet. It is similar to the electric field of the charged particle and is represented by the magnetic field lines. The denser the magnetic field lines the higher the strength of the magnetic field.
