magnetic declination according to Sky

Sky News reports that "the angle a compass needle makes between true north and magnetic north is called declination".

From where do journalists get their information ?

I have written to the editor.

If I get a reply, which I do not expect, I shall update you.

I wouldn’t bother - it’s bound to be full of either variation or deviation.....

"Variation" in French is "Declinaison" and is sometimes translated by "Declination" in English... may be a French journalist not used to Navigation? Declination is not technically wrong, it is the angle in the H plane between Magnetic N and True N... at a given point.

Then please tell me what the vertical angle between a line of magnetic flux and the local horizontal is called.

Try a google search for magnetic declination and another search for magnetic inclination. You may be surprised at what it reveals. And it is not just Wikipedia which says that declination and variation are the same thing.

Well Keith, to think I taught rubbish to our students for all that time, as did Roger and Pete across the road.
….and didn't we always tell our Kingston students to avoid Wiki in their assignments ?

Bergerie, dip = declination.

Dip is Inclination.

Variation is Declination.

I was absolutely astounded when I first found this on the internet a few years ago.

If an uphill path is called an inclination, then what is a downhill path called ?

Talk for a minute on the subject without err or hesitation.

I once had the opportunity of working with a young female journalist who went on to much greater things.She was putting on her makeup in the truck I was operating and turned around to ask me how I got involved in the business.
I replied I had a good background in RF engineering, and that I was over-qualified for journalism.
"Why is that?" she asked.
"I can read and write," I replied.

One of the explanatory articles referenced (since deleted!) said that the slow and unpredictable changes in declination, etc., were due to continental drift. Since it has changed by 16 degrees here in my lifetime, I guess Scotland must be drifting at quite a rate.

Well the Scots do appear to a thing about wanting to go off on their own?

Yes, I'm not quite sure why this thread is necessary at all.
