Magnetic field - Wikipedia

Magnetic field lines form in concentric circles around a cylindrical current-carrying conductor such as a length of wire. The direction of such a magnetic field can be determined by using the "right-hand grip rule" see figure at right . The strength of the magnetic field decreases with distance from the wire.

What is Magnetic field intensity? Electricalvoice

Magnetic field intensity is defined as the degree to which the magnetising field can magnetise a material. The magnetic field which magnetises a material placed in it is known as the magnetising field. Magnetic field intensity is denoted by ‘H‘ and also known as intensity of magnetising field or magnetising force.
