Question

State the characteristics of magnetic field lines.

Answer 1

- Hint: To solve this question, we will see different properties of magnetic field lines. Magnetic field lines are imaginary lines. We can draw magnetic field lines to visualise the magnetic fields of a magnetic pole. Also the magnetic poles always exist in pairs but we can visualize as single and and the other pole at infinity.

Complete step-by-step answer:
The properties of magnetic field lines are
A magnetic field line is a hypothetical line such that tangent to this line at any point gives the direction of the magnetic field line at that point.
Relative density of magnetic field line at any two points gives an idea about intensities of magnetic field at the two points.
Two magnetic field lines can never intersect each other because there can’t be two directions of magnetic field vectors at a point.
Magnetic field lines originate from the North Pole and terminate at the South Pole.
Uniform magnetic field lines are represented by parallel equally spaced lines.
Magnetic field lines always form closed loops.

Note: The magnetic force is only a little bit different from the magnetic field. The force is what is felt by a magnet. It is determined by the field and the magnet, and so is not strictly a property of the field. Magnetic field lines and electric field lines are similar in the sense that the properties of the lines are similar, the only difference is that we have to replace magnetic poles with electric charge.
