Magnetic field lines is considered one of the most asked concept.
12 Questions around this concept.
The magnetic lines of force inside a bar magnet
Three identical bars A, B and C are made of different magnetic materials. When kept in a uniform magnetic field, the field lines around them look as follows :
Make the correspondence of these bars with their material being diamagnetic (D),ferromagnetic (F) and paramagnetic (P) :
Important points regarding Magnetism-
i.e If a magnet is broken into a number of pieces each piece becomes a magnet.
Magnetic field-
Space around a magnetic Pole or magnet or current-carrying wire within which its effect can be experienced.
Magnetic field lines-
The magnetic field line is not real. The magnetic field lines are a visual and intuitive realization of the magnetic field.
Properties of magnetic field lines-
For the below figure The tangent to the magnetic field line at point P represents the direction of the net magnetic field () at point P.
