in the case of materials some of the atoms or ions in the material have a net magnetic due to unpaired electrons in partially filled orbits. however
diamagnetism is a basic property of all matter though it is generally very weak. it is due to the no cooperative behaviour of oepenrbiting electrons
consider a current loop where the circulating current is i. this may be for an example of a coil carrying a current. we will assume that the

it is the property of a material by virtue of which it allows itself to be magnetized. permeability varies from material to material depending upon
it is defined as the magnetic lines of force per unit area of the pole face.
there are imaginary lines or path of the field in the given direction. the lines of force are assumed to make a closed path beginning from n pole
it is the force that the field would exert on any unit magnetic pole placed in the field. it is also known as magnetic
it is the area or region around the material where magnetic properties can be found is called as ldquomagnetic
materials which can be magnetized are called magnetic materials. when magnetized such materials create a magnetic field around them. some of the
