The Meaning of the Statement:

The statement "The direction of the magnetic field at a point is the direction of the resultant force acting on a hypothetical north placed at that point" refers to the relationship between the magnetic field and the force experienced by a hypothetical north pole in that field. It states that the direction of the magnetic field is the same as the direction in which a north pole would be pushed or pulled if it were placed at that point.

Explanation:

The magnetic field is a region in which magnetic forces are experienced. It is produced by moving electric charges or magnetic materials. The statement suggests that if we consider a hypothetical north pole and place it at a specific point in a magnetic field, the direction of the force it experiences will determine the direction of the magnetic field at that point.

Key Points:
- Magnetic fields are represented by lines of force that indicate the direction of the force experienced by a north pole.
- The force experienced by a north pole in a magnetic field is perpendicular to both the field direction and the velocity of the north pole.
- The force acting on a north pole is zero when it is placed parallel or antiparallel to the field lines.
- When a north pole is placed at an angle to the field lines, it experiences a force that tends to align it with the field.
- The direction of the force acting on the hypothetical north pole represents the direction of the magnetic field.
- The magnetic field lines form closed loops and are continuous.
- The strength of the magnetic field is determined by the density of the field lines, with closely spaced lines indicating a stronger field.

Conclusion:
In summary, the statement implies that the direction of the magnetic field at a point can be determined by analyzing the force experienced by a hypothetical north pole placed at that point. This understanding allows us to visualize and study magnetic fields by considering the forces acting on magnetized objects.
