magnetic field is a region of space where a north magnetic monopole experiences a force. The direction of the field is by definition the direction of the force on the north end of a magnet. Since most texts contain diagrams of magnetic fields they will not be reproduced here.
A static magnetic field can exist in a good conductor. When the conductor carries current, it produces the flux which can exist inside the conductor. Due to this flux, magnetic field and intensity at a point inside the good conductor.
The shape of the magnetic field lines around a straight current-carrying conductor is circular, with the conductor at the center of each circular loop. These magnetic field lines form concentric circles around the conductor, perpendicular to the direction of the current flow.

Hall effect can be used to measure the strength of a magnetic field. When a current passes through a conductor in a magnetic field, a Hall voltage is generated perpendicular to both the current and the magnetic field. By measuring this Hall voltage, the strength of the magnetic field can be calculated.
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
A changing magnetic field induces an electric current in a conductor.
The speed of the conductor through the magnetic field, which translates into the number of magnetic lines of force the conductor can cut per unit time, will determine the magnitude of the voltage induced in the conductor. As an additional factor, if a longer piece of wire can be moved through the magnetic field, it will induce more voltage as well. The more speed we can put on the conductor, and the more of the conductor we can move through the magnetic field, the more voltage we can induce in the conductor.
When a current-carrying conductor is placed in a magnetic field, a force is exerted on the conductor due to the interaction between the magnetic field and the current. This force is known as the magnetic Lorentz force and its direction is perpendicular to both the magnetic field and the current flow. The magnitude of the force depends on the strength of the magnetic field, the current flowing through the conductor, and the length of the conductor exposed to the magnetic field.
When electrons move through a conductor, they create a flow of electrical current. This flow of current generates a magnetic field around the conductor in accordance with Ampere's law. The strength of the magnetic field is directly related to the magnitude of the current and the distance from the conductor.

Magnetic field intensity speaks of the strength of a magnetic field, usually in Tesla, whereas forces deal with units of Newtons and are fundamentally characterized through F=MA in conjunction with Newton's Laws.
When a direct current (DC) flows through a conductor, it generates a magnetic field around the conductor. This phenomenon is described by Ampere's law, which states that a magnetic field is produced around a current-carrying conductor. The strength of the magnetic field is directly proportional to the current flowing through the conductor.
