Question

Which of the following is not true about
magnetic field lines?
A: They always north to south
outside magnet
B: They always south to north
inside the magnet
C: They always north to south
inside the magnet
D: They have tangential direction at
curves​

Answer 1

The wrong statement is they always move from north to south inside the magnet.

Answer:

Option c is incorrect.

Explanation:

• Magnetic field of lines are imaginary closed continuous curves.

• They never intersect each other.

• The tangent at any point on the curve, gives the direction of magnetic field at that point.

• Magnet exist as dipole having two poles of north and south.

• Magnetic monopole does not exist. It is impossible for a magnet to have a single pole.

• Magnetic filed lines originates from north pole and ends at south pole outside the magnet. They move from north to south outside the magnet.

• Magnetic field lines move from south to north inside the magnet.

• The lines get crowded near the poles , where the strength is maximum.
