    Clear explanation .
    Once you've calculated magnetic declination for the current year. I think it's easier to skip the rest of the math to set / point the compass to the correct direction. If mag declination is 15 degrees west, turn the compass dial 15 degrees CCW. If it's 15 degrees east, turn the compass dial CW 15 degrees.

    Sir, I want to ask why does magnetic declination get bigger over time. For example, 2000 the magnetic declination is 7' and for 2024 it is 20'. Or something like that. You mentioned that at around 0:58 and 1:05. What I am asking is, "why does the magnectic declination change over time?"
    Hope you respond soon. I need to answer the question today for my task. i.o.w. I need an answer now for my question lol because i need to give in my task today.

    What about back bearing. Compass heading set on magnetic north = 0° Back bearing should be South = 180° but compass reads 190° Should you then always subtract the declination value to get to the righ back bearing regardless of the forward bearing. Hope it makes sense

    • @fish9529
      @fish9529  6 років тому +3

      Hi Freddy, thanks for the question. The 95' next to the 13° is the same as 1° and 35'. This is the case since 60'=1° (there's only 60 minutes in one degree), and then you have 35' left. So then you add that 1° to the 13° which is already there, and write the remaining 35' next to it. Hence, 14°35'. I hope this answers your question.

    • @fish9529
      @fish9529  3 роки тому

      Hi, firstly you need to find out the most recently updated magnetic declination for your starting point as this changes all the time. You can do an online search to find this out. Once you know the declination, you can work it out. It can be quite complicated to explain, but I have posted a video on the 3 different norths which might help.

    • @fish9529
      @fish9529  6 років тому

      Hi there, good question. Let's zoom in on the 95 minutes and forget about Geography for a moment. 95 minutes can also be written as 1 hour and 35 minutes. We know that 60 minutes = 1 hour, but don't forget about the remaining 35 minutes. That's how we get to one hour and 35 minutes. BUT, remember that we are not working with time here. In this case, we have degrees and minutes. One degree is similar to one hour, in that we have 60 minutes in one degree. So if we take 60 minutes (out of the 95 minutes) and write it as one degree, we should add it to the 13 degrees we've already got. This will give us 14 degrees, with 35 minutes remaining. That's why we write 14 degrees 35 minutes instead of 13 degrees 95 minutes. I hope this answers your question. All of the best with the studies!

      @fish9529  2 роки тому

      Hi, are you talking about that 13°95' at 4:44? The reason we change that is because there's only 60 minutes in one degree, in other words, 60' = 1°. So, you already have 13°, and then you take 60' (one degree) from the 95'. Add this 1° to the 13° and then you have 14° plus the 35' that's left. Hence the answer: 14°35'. I hope this helps. If I misunderstood your question, please let me know. I hope the exam goes well!

    • @fish9529
      @fish9529  Рік тому

      Hi, I just made it up and used it as an example. In the video, I call it "normal" bearing but to be more specific, one should talk about either true bearing or grid bearing. This means, you use either true north or grid north in order to measure the bearing. Many people argue that the difference between true north and grid north is so small that it can be ignored, but you should pay close attention to your teacher and find out exactly what they want. You can watch my other video on how to do a "normal" bearing here: ua-cam.com/video/T40AMljjgrU/v-deo.html
