• Magnetic Compass Error...
The coolest explanation 👌 2024
Music is distracting but good explanation
Thanks for the feedback Jeff. Got carried away with the music a little.
@@flightclubonline 🤣
Nah the music's great
The best explanation out there
Thank you!
instead of ANDS for North Acceleration South Deceleration, the better pneumonic would be NADS- which also suggests this only applies to the northern hemisphere
how the fuck can i remember this holy molyyyyyyyyy
Thank you so much made it easy to understand 👍👍😃
You're welcome!
I didn't get this. Any other video to understand this concept please?
Respected sir/madam your lectures are great. I am really getting a lot. Thanks so much. Can you please elaborate it in more detail as non-professionals like me would like a bit more detail to comprehend. By the way i am a Doctor and a hobbyist MSFS user.
so basically if you're not flying straight and level, just ignore the magnetic and use the gyro?
Isn't there a basic error here? Whether the compass magnet is dead level or tilted 85 degrees, won't the center of gravity be the same,-smack in the middle of the magnet? What the dip causes is an offset between the center of gravity of the magnet and the pivot point around which the magnet will tend to turn, because that point is directly below the jeweled cup upon which the magnet/card assembly rests AND pivots. Hard to visualize, but the CG, (the little circle with quadrants) doesn't change. It's the center of rotation that changes.
You are absolutely right. The center of gravity is always the same as the mass distribution within the magnet does not change (centre of gravity is defined in physics as the sum of all static products of inertia divided by the total mass)
Hi Dan, thanks for your contribution. I think what you describe here is exactly what we demonstrate in this video from 0:45.
@@flightclubonline no.
@@flightclubonline Excellent work, but one request the music is distracting. In my opinion, in any serious or technical discussion, background music only adds to the background noise.
I bought a Feng Shui compass in Taiwan yesterday. When I took it to Sydney, I found the needle points down. Is my compass broken?
Because it's from northern hemisphere, won't work in southern hemisphere
.au oh it's southern hemisphere
0:55 why does the dip cause centre of gravity shift? I need some help about physics (I almost forgot all Newtonian Mechanics learned in school) Please help me
The compass (magnet) is suspended like a pendulum. Near the equator, the magnet will be suspended straight down. When closer to the south/north pole, the magnetic lines are "going into" the earth, which makes the magnet want to orient itself going into the earth. The only way to do it would be to offset from the straight down position. So, swings to the right near the north pole and swings to the left near the south pole. So, the center of gravity also offsets in the same direction. I hope this makes sense.
why there are those differences in north and southern hemisphere?
In the northern hemisphere, the north side of the compass dips down while in the southern hemisphere, the south side of the compass dips down. This is because the compass tends to align itself with the magnetic field lines, which always point from south to north. Since the center of gravity of the compass is shifted towards the opposite end of the dip, the center of gravity will be on the south side of the compass in the northern hemisphere, while the CG will be shifted towards the north side of the compass in the southern hemisphere.
i.e. imagine at 0:45 that the compass was at 40 degrees north instead of south. The north side of the compass (the red side) would dip down instead of the south side (grey side).
Wouldnt the center of gravity be shift to the dip side of the compass rather than the lifted side?
Don’t forget about magnetic declination! 😉
You should turn off the music
no you shouldn't
Unfortunately too late for that now but will tone down the tunes for next time. Thanks for your feedback.
@@flightclubonline The music choice really wasn't all that bad - it was maybe just a smidge too loud. Yes, maybe consider turning the soundtrack down a bit when producing subsequent videos? BTW: Your animations helped me understand this better than all the other resources I've tried. Kudos!
Thanks Australians for confusing most of the world (northern hemisphere).I wonder how many students marked this wrong and didnt know the video makers are australians.
Hello there from down under. The video clearly states 'Southern Hemisphere' but similar principles apply to the Northern Hemisphere. Use ANDS in the Northern Hemisphere.
Why are the video's made from a southern hemisphere perspective? Down under flight school?
because Australia is in the southern hemisphere bro
Thanks, man! I was about to be crazy that why (ANDS) acronym is not matched with this video... The admin should change the title and inform this
@@cyrus_the_pilot ok, only if every northern hemisphere video stipulates that they are in the northern hemisphere too....... I am guessing you are from America?.. America is not the only country in the world hahah
@@MrJoele21 I am not sure what are you talking about.
Could you turn the music up any louder please? Thanks
This is only for those who already know what you are talking about. It is explained too fast for those who see this for the first time. Luckily I went thru other material in the past, but unfortunately after watching this vid I had to go back to that material because you just made it more confusing with a very superficial explanation. Other parts vids are okay, this is quite of a mess, oversimplifying the topic
This is designed for ATPL-A students. Its a perfectly concise explanation for its target audience :)
