What would happen if walkers did not adjust their compass readings to account for magnetic variation?
They would not arrive at the correct location.
True north refers to the rotational pole. Compasses point roughly towards the magnetic pole. I say roughly because geographic and man made features can distort the magnetic waves. The rotational and magnetic pole are not at the same place. Most maps are drawn according to the rotational pole (true north).
What else can I help you with?
What effect does magnetic variation have on the earths orientation?
Magnetic variation affects the angle between true north and magnetic north, resulting in differences in the Earth's orientation for navigation and mapping purposes. This variation can impact the accuracy of compass readings and navigational systems that rely on magnetic north.
Why is magnetic Declination is important?
Because if you need to use your compass to figure out which direction is north,then you need to know by how much the direction the compass points is wrong,and which way. That's the magnetic declination.
What characteristic of iron would make it a bad material for housing a compass?
It is magnetic and would throw off your little dial
Different magnetic deviation and magnetic variation?
In relation to aviation... Deviation is the difference between a true heading and the compass heading. The compass heading is different from true due to magnetic fields induced by the components of the aircraft. Variation is the difference (angle) between True North and Magnetic North. Variation changes depending on your position and is normally indicated on maps as a dashed line with the variation in degrees along that particular line.
What characteristic of iron would make it a bad material for the housing around a compass?
It could not be used because it attracts magnets and a compass is a specialist form of magnet, utilising the magnetic properties of the earth to give a reading. Compass housings are invariably made of brass, aluminium or plastic.
What will happen if the walkers did not adjust their compass readings to account for magnetic variation?
If walkers do not adjust their compass readings for magnetic variation, they could end up navigating in the wrong direction. Magnetic variation means the difference between true north and magnetic north, so failing to adjust for this can lead to significant errors in their navigation. It's essential for accurate orienteering and avoiding getting lost.
What effect does magnetic variation have on the earths orientation?
Magnetic variation affects the angle between true north and magnetic north, resulting in differences in the Earth's orientation for navigation and mapping purposes. This variation can impact the accuracy of compass readings and navigational systems that rely on magnetic north.
What was the disadvantage of using a compss to determine direction?
A compass may give inaccurate readings if it is near a magnetic field, metal objects, or electrical devices which can interfere with its accuracy. Additionally, compass readings can be affected by variation and deviation which may need to be compensated for to determine true direction.
What metal makes compass go haywire?
Iron can make a compass go haywire as it can create magnetic interference. When a compass is near iron or magnetic objects, it can disrupt the Earth's magnetic field that the compass relies on for accurate readings.
Why is magnetic Declination is important?
Because if you need to use your compass to figure out which direction is north,then you need to know by how much the direction the compass points is wrong,and which way. That's the magnetic declination.
A way to find the variation from true north?
To find the variation from true north, you can use a magnetic compass to determine the magnetic north and then calculate the angle between the magnetic north and the true north. This angle is known as the magnetic declination or variation. Many maps and GPS devices provide information about the current magnetic declination in a specific location.
What is magnetic variation?
Magnetic variation is the angle between true north (the direction pointing to the North Pole) and magnetic north (the direction a compass needle points). It varies depending on location and changes over time due to shifts in the Earth's magnetic field. Pilots and navigators use magnetic variation to accurately navigate using a compass.
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.

What is compass error?
Compass error refers to a magnetic compasses natural tendencies to produce erroneous readings in certain circumstances. Sometimes this may be due to environmental effects such as proximity to a strong magnetic field. Compass error is also frequently the result of shortcomings or anomalies in the way compasses work. Compass error due to environmental effects usually refers to an airplanes compass being drawn toward the magnetic fields generated by the aircrafts engines. This is called magnetic deviation. Additionally in some regions with high concentrations of iron in the soil, compasses may give all sorts of erroneous information. Magnetic compass "variation" deals with the difference between the magnetic north pole (which magnetic compasses point to) and the true north pole (the actual geographical north pole.) While this difference may seem minor, magnetic variation can mean a difference of up to 4 or 5 degrees in some places. In aviation, compasses may also give erroneous readings when turning or performing other maneuvers. This is due to the curvature of the earth combined with the fact that the compass needle wishes to point at the magnetic north pole. Since the earth is round, and the compass points to the magnetic north pole, the compass needle will in most cases be drawn to a point below the horizon from the users standpoint. This will cause the magnetic compass to precede when turning to a northern heading, and to lag when turning to a southern heading.
What would happen if people did not adjust there compass readings to the account of true north?
They would not arrive at the correct location. True north refers to the rotational pole. Compasses point roughly towards the magnetic pole. I say roughly because geographic and man made features can distort the magnetic waves. The rotational and magnetic pole are not at the same place. Most maps are drawn according to the rotational pole (true north).
How does one measure magnetic variation?
Magnetic variation (also known as magnetic declination) is often indicated on maps. But if the magnetic variation of a location is unknown, a declinometer can be used. Basically, this tool determines the angle between the celestial pole (roughly indicated by the North Star in the northern hemisphere) and the magnetic pole (indicated by a compass).
