We know that a magnet attracts small pieces of iron even when they are lying at a certain distance away from it . Thus , the magnetic force , like the electric force or the gravitational force , acts at a distance. The idea of force acting at a ‘ distance' can be easily understood by introducing the concept of a field . We imagine a magnet as giving rise to a magnetic field, which exists, in the whole space surrounding it.
The phenomenon of magnetism is "mediated" by the magnetic field -- i. e ., an electric current or magnetic dipole creates a magnetic field, and that field, in turn, imparts magnetic forces on other particles that are in the fields.
All materials are influenced by magnetic field to greater or lesser degree .
Magnetic Field
Space around a magnet in which magnetic force is exerted is called a magnetic field.
Bar Magnet
The space around a magnet in which the force of attraction and repulsion can be detected is called the magnetic field.
The force that one magnet exerts on another can be described as the interaction between one magnet and the magnetic field of the other . As in the case of an electric field , placing a `test object’ at that point and finding the force that the field exerts on it can measure the strength of the magnetic field at any point . The test object is chosen to be unit North Pole . The strength of magnetic field at a point of space surrounding a magnet is defined as the force experienced by a hypothetical unit North Pole placed at that point and the direction of the force gives the direction of the field. Magnetic field is a vector quantity that has both direction and magnitude. The direction of the magnetic field is taken by convention that the field lines emerge from North Pole and merge at South Pole. The strength of the magnetic field can be observed from the degree of closeness of the field lines .

magnetic field
----------------------
magnetic field is the region around the magnet where there is a magnetic effect and there will be a force of attraction and repulsion in this region and out side the magnetic field there is not such force involved
----------------------------------------------------------------------------------------------
magnetic field lines
--------------------------
they are the lines which is used to represent the direction or magnitude of the magnet where there is a presence of magnetic field and it also shows the strength of the magnetic field and it is a vector quantity
