In the case needle method, the direction of the magnetic meridian is established at each traverse station and the direction of the line is determined with reference to the magnetic meridian. In other words, the magnetic bearing of each line is determined directly. A theodolite fitted with a compass is used for determining the magnetic bearing of the traverse line. The loose needle method is also know as free needle method.

Loose needle method
The loose needle method is a technique used in traversing to determine the direction of a line with reference to the magnetic meridian. This method involves establishing the direction of the magnetic meridian at each traverse station and then determining the direction of the line based on this reference.
Establishing the magnetic meridian
- The magnetic meridian is an imaginary line that represents the direction of the Earth's magnetic field at a specific location.
- At each traverse station, a compass is used to establish the direction of the magnetic meridian.
- The compass needle aligns itself with the Earth's magnetic field, pointing towards the magnetic north.
- By observing the compass needle at each traverse station, the direction of the magnetic meridian can be determined.
Determining the direction of the line
- Once the magnetic meridian is established at each traverse station, the direction of the line can be determined by measuring the angle between the line and the magnetic meridian.
- This can be done using a theodolite, which is a surveying instrument used to measure angles.
- The theodolite is set up at each traverse station, and the angle between the line and the magnetic meridian is measured.
- This angle is known as the bearing of the line and is usually measured in degrees, minutes, and seconds.
Advantages of the loose needle method
- The loose needle method is relatively simple and straightforward.
- It does not require complex equipment or calculations.
- It is a practical method for determining the direction of a line in the field.
- The loose needle method is commonly used in traversing for its simplicity and efficiency.
In conclusion, the loose needle method is a technique used in traversing to determine the direction of a line with reference to the magnetic meridian. It involves establishing the direction of the magnetic meridian at each traverse station and then determining the direction of the line based on this reference. This method is simple, practical, and widely used in the field of surveying.
