Question

State the characteristics of magnetic field lines.​

Answer 1

Answer:

Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:

• The field is tangent to the magnetic field line.
• Field strength is proportional to the line density.
• Field lines cannot cross.
• Field lines are continuous loops.

Answer 2

Answer:

Some important properties of magnetic field lines are listed below –

• 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.
