Determination Of Dip Using A Dip Circle

APPARATUS REQUIRED:

 
• Dip circle 
• Magnetized needle 
• Plumb line 
• Leveling screws 
• Adjustable spirit level 
• Stopwatch

THEORY:

The dip angle (angle of inclination) can be determined using a dip circle, which consists of a magnetized needle and a graduated circle. The dip is measured by aligning the needle with the magnetic field and observing the angle of inclination.

PROCESS:

 
1. Set up the dip circle on a stable surface using leveling screws. 
2. Ensure the needle is magnetized and mounted horizontally. 
3. Align the dip circle with the Earth's magnetic field using the adjustable spirit level and plumb line. 
4. Read the dip angle directly from the graduated circle. 
5. Repeat the measurement for accuracy and calculate the average dip angle.

OBSERVATIONS:

Dip angle observed: 60 degrees

OBSERVATION TABLE:

                         

Observation	Dip Angle (degrees)
1	60

CALCULATION:

Calculate the average dip angle if multiple observations are made.

RESULTS:

The average dip angle observed in the laboratory is 60 degrees.

PRECAUTIONS: 

1. Ensure the dip circle is properly leveled. 
2. Check the magnetized needle for proper alignment. 
3. Avoid any magnetic disturbances in the vicinity. 
4. Repeat measurements for accuracy. 
5. Record observations promptly to minimize errors.
