The \( _{--}-_{-}-_{-}- \) drawn at any point on the magnetic lines of force gives direction of magnetic field at that point.

1. tangent
2. perpendicular
3. chord
4. None

Correct answer: tangent

Solution

Magnetic field lines show the direction of the magnetic field at each point. The direction at a specific point is along the tangent to the field line there, not across it or along a chord.
