The magnet or moving electric charges both produce a magnetic field. The area where the force of magnetism acts around the magnetic material or a moving electric charge is known as the magnetic field. Magnetic field lines are used to depict magnetic fields. It is a tool for visualising the magnetic field’s strength and direction. A compass needle can be used to sketch magnetic field lines. On a paper piece near the magnet, place the compass needle. Verify and note the direction toward which the compass needle is pointing. Mark the directions as you rotate the compass needle in various directions. The magnetic field lines can be seen by connecting the locations.
The following is a list of some crucial magnetic field line characteristics:
- The magnetic field’s direction is shown by the tangent drawn to the field lines.
- The field’s strength is directly inversely related to the density or closeness of the field lines.
- The north pole appears to be the origin or beginning of magnetic field lines that combine or come to an end at the south pole.
- The magnetic field lines within the magnet run from the south pole to the north pole.
- Never do magnetic field lines cross one another.
- A closed loop is formed by magnetic field lines.
- At any point on the field, field lines have both a direction and a magnitude. As a result, a vector is used to represent magnetic field lines.
- They serve as a marker for the magnetic field’s direction.
