Detailed Solution

Concept- The direction of a magnetic field at a point determined by compass. The magnetic field is located at a specific spot indicated by the magnet's field lines. Field lines indicate the direction of the magnet's field lines. They also show the direction of the magnetic force. These lines allow us to rapidly calculate the magnetic force and magnetic field.
We now know where to look to find the direction of the magnetic field. It is known that magnetic field lines are emitted from the North Pole and merge at the Magnet's the South Pole. Magnetic field line characteristics: Magnetic field lines from the North Pole merge at the South Pole. The magnetic field's strength can be determined by how closely the field lines are packed together.
Hence, the correct answer is the compass.
