What is local attraction and how can we minimize its effect in compass surveying?
Wiki User
∙ 7y ago
Local attraction refers to the effect of nearby magnetic objects on the accuracy of a compass survey. To minimize its impact, you can keep the compass away from metal objects, power lines, or electronic devices, take multiple readings and average them, or use a different type of compass like a gyrocompass which is less susceptible to local attraction.

How would a southern hemisphere compass differ from a northern hemisphere compass?
The Southern Hemisphere compass will naturally align it self with the South Poleanswer 2 A compass designed to work in the southern hemisphere will have the needle/card balanced differently, for in the S hemisphere the S pole will cause the compass to dip slightly - and opposite to the northern hemisphere.The compass manufacturers divide the Earth into five zones for balance. Some folk need a compass that is insensitive to this effect, (e.g. Army) and for this they choose to have the needle a smaller part of the weight balanced on the pivot, and have a liquid filled compass.Regarding the first sentence above, the compass needle actually aligns itself with the lines of magnetic force at your location - which will still result in a N - S alignment.
How did the compass effect the world today?
The compass revolutionized navigation by allowing sailors to determine their direction at sea. This led to greater exploration, trade, and cultural exchange between countries, eventually shaping the geopolitical landscape of the world today.
How do flood affect agricultural land?
Floods can have a devastating effect on agricultural land as they can cause soil erosion, waterlogging, and deposition of sediments which can degrade soil fertility. Excessive flooding can also destroy crops, drown livestock, and damage agricultural infrastructure, leading to significant economic losses for farmers. Proper drainage systems and flood management strategies are crucial to minimize the impact of floods on agricultural land.

What direction does the Coriolis effect cause currents in the northern hemisphere to turn?
In the northern hemisphere, the Coriolis effect causes currents to turn to the right. This means that ocean currents tend to flow clockwise in the northern hemisphere as a result of the Coriolis effect.
What is local attraction on compass survey?
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.
How do you eliminate local attraction?
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.
