31. Explain characteristics of magnetic field lines.
Answers
Magnetic field lines emerge from the north pole and merge at the south pole.
As the distance between the poles increases, the density of magnetic lines decreases.
The direction of field lines inside the magnet is from the South Pole to the North Pole.
Magnetic lines do not intersect with each other.
The strength of the magnetic lines is the same throughout and is proportional to how close are the lines.
Answer:
features of magnetic field lines
Explanation:
● The tangent drawn to the magnetic field lines gives the direction of the magnetic field.
● The closeness or density of the field lines is directly proportional to the strength of the field.
●\Magnetic field lines appear to emerge or start from the north pole and merge or terminate at the south pole.
● Inside the magnet, the direction of the magnetic field lines is from the south pole to the north pole.
● Magnetic field lines never intersect with each other.
Magnetic field lines form a closed-loop.
● Field lines have both direction and magnitude at any point on the field. Therefore, magnetic field lines are represented by a vector.
● They denote the direction of the magnetic field.
● The magnetic field is stronger at the poles because the field lines are denser near the poles.
