Which of the following statements is correct ?
The correct statement is: (D) Tangent at a point on every field line gives the direction of magnetic field at that point. Magnetic field lines are continuous closed loops and never intersect each other. They represent both the direction and strength of the magnetic field.

The correct statement is: A tangent at a point on every magnetic field line gives the direction of the magnetic field at that point. This is a fundamental property of field lines. The other statements are incorrect: magnetic field lines do form closed loops, they don’t begin or end, and they never intersect.
Answer: (D) Tangent at a point on every field line gives the direction of magnetic field at that point.
