GEOLOGY

Detailed explanation-1: -Magnetic field lines always form a closed loop. Outside the magnet, they go from the north pole to the south pole. Inside the magnet, they go from the south pole to the north pole. The field lines never intersect each other.

Detailed explanation-2: -Magnetic field lines never cross. Magnetic field lines naturally bunch together in regions where the magnetic field is the strongest. This means that the density of field lines indicates the strength of the field.

Detailed explanation-3: -There will be two directions of the field at the same point.

Detailed explanation-4: -The given statement about the magnetic field is TRUE. The magnetic field is the area where a magnet has the greatest influence on other objects, such as magnetic materials or electric current.

Detailed explanation-5: -Each point on the field line gives the direction of magnetic field. Now if two magnetic field line intersect each other then at that point there will be two direction of magnetic field which is not possible.
