If you are navigating by compass, you should correct for magnetic declination as a compass can point up to 20 degrees off from true north, depending on your location! While true north is a fixed point, the loca

ortrue north. Rather, it aligns itself with the direction of the Earth's magnetic field, showingmagnetic north. In most locations on Earth, magnetic north differs from true north, so magnetic declination has to be taken into account.
Answer to Annie: Shifting from true to magnetic is just a change of reference, It doesn't change just because the bearing you want is between the two. U.S army maps also have Grid North, because the grids printed on them aren't always aligned with true north. Does anyone know why?
In the presence of a magnetic field, a torque (twisting force) pushes that needle to point north. How much torque does it feel in the earth's 0.5 gauss field? That force is directly related to the strength of the magnet. The stronger the magnet, the more torque. This torque is what ...
Example of north arrows on a US Topo map. Star is True North, GN is Grid North, MN is Magnetic North. Image: USGS, public domain. Shifting Magnetic North James Ross located the pole for the first time on June 1, 1831 at Cape Adelaide on the Boothia Peninsula in Nunavut’s northern ...
As it's rolling, the magnetic torque is trying to align the magnet to the ambient magnetic field, just like a compass needle points north. What is a dipole moment? We dropped that word "dipole" without much discussion earlier. We see "dipoles" mentioned in a lot of places. What exactly...
Flexible magnet stick to small calculator can be attached to the wall now! Pin magnets can even hang some keys 🙂 The magnetic paint that was used: http://titan-magnetics.com/product/magnetic-paint-1-litre/ but like Kristie said, magnetic paint strength cannot be compared to a sheet of ...
However, one should bear in mind that a recent RCT also found no advantage to any technique [59]. Finally, there were variations in biopsy technique between studies. For example, by the number of cores taken, or whether TRUS-GB or MRI-GB was performed first. If the former is true then...
