Question

Inside the magnet, the field lines move from the south pole to the north pole. Is this statement true?

• A. True
• B. False

Answer 1

The correct option is A True

Magnetic field lines

1. Magnetic field lines are the imaginary field lines that start from the north pole and end at the south pole.
2. But inside the magnet, the field lines go from the south to the north pole.
3. The tangent drawn at any point of magnetic field lines gives the direction of the magnetic field at that point. This concept shows that magnetic field lines do not intersect each other.

The direction of magnetic field lines

1. At the outside of the magnet, the direction of the field lines is from the north pole to the south pole.
2. At the inside of the magnet, the direction of the magnetic field lines is from the south pole to the north pole.

Magnetic inside the magnet

1. This strength will maximum when the two poles are at a minimum distance. Inside the magnet, the field lines go from south to north. So, on the outside of the magnet, the field lines leave from the north pole and enter from the south pole.
2. We know, the earth is a magnet and it has a south and north pole. By the influence of the earth's magnetic field, the field lines go from south to north.

Thus, inside the magnet, the field lines move from the south pole to the north pole, this statement is true.
