Representation of Magnetic Field
The magnetic field around any magnetic material can easily be shown by two categories which are,
- Magnetic Field Vector
- Magnetic Field Lines
Magnetic Field Vector
We can represent a magnetic field with the help of the vector and these vectors are called magnetic field vectors. These vectors are drawn around the magnetic material and the direction of the magnetic field at any point is defined by the direction of the magnetic field vector at that point. The strength of the magnetic field can also be explained by magnetic field vector, the higher the magnetic field vector the higher the is the strength of the magnetic field.
Magnetic Field Lines
Magnetic field of the magnetic material can also be easily represented by magnetic field lines. These lines start from the North pole of the magnetic and end at the south pole of the material forming a complete closed loop. The direction of the magnetic field at any point is defined by the direction of the tangent at that point. The strength of the magnetic field is also explained by magnetic field lines, the denser the magnetic field line the higher the is the strength of the magnetic field.
The image given below shows the magnetic field lines around a bar magnet if similar poles are taken together and if the opposite poles are taken together.
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.
