While being very bored, I decided to hang a magnet in
the shape of a bar to see how good it is compass-wise.
Apparatus: string, cotton thread and the magnet.
Result was, when it had a stable position, it pointed
East-
West.See pic.
I'm sure it's more traditional with a bar-shape magnet
to
be N-S, but maybe there are E-W bar magnets?

There are; or rather, there are bar magnets where the domains aren't orentated along the major axis, but normal to it. |
|
| |
If you heat a magnet above its Curie point, then let it cool in a strong field, you can align the magnetism in any orientation you want. It"s just easiest to make rectangular magnets with the "standard" pole disposition. |
|
| |
Then again, the overdue planetary field reversal might suddenly have started in your neighbourhood .... |
|
| |
Although this is something I am normally loth to do, on this
occasion I have to agre... agr.... agree with... Nope. Can't
do it. Let me instead say that the foregoing annotation may
not be completely incorrect. |

What you have is not a long, thin EW magnet, but a short
and very wide NS one. |
|
| |
Moreovermore, if it *were* an EW magnet, then one end of
it should point to Greenwich so, if you're in the UK, you'd
have to consider exactly where you were. |
|
| |
The answer is "uncomfortably close to South-East London", which is true of anywhere in the mainland UK. |

A quite magnificent effort, [MB]. We have always known that you have some Royal blood. |
|
| |
Perhaps the problem is that you seem to have used a large
grasshopper or praying mantis in place of string to hold up
your magnet. |
|
| |
No, it clearly says "Sting" on the caption, something which neither mantis nor grasshoppers have. |

Where is Ivorth, by way ? It is unknown to Google Maps. |
|
| |
Besides, the very subtle, almost undetectable, way in which the image has been digitally manipulated completely destroys the credibility of the experiment, |
|
| |
Regrettably, it is actually true, and I have the lowest
drawing skills of all mankind. It's me age. |
|
| |
Anyway, I'm still wondering why would make a job lot
of "short and very wide NS" magnets. |
|
| |
NB there is a Ivorth Luhulima on Instagram, whatever
that is. |
|
| |
There was also some sort of Welsh electronic train called
Ivorth e-Engine. |
|
| |
According to the net - so it must be true - "Means
"handsome lord" from Welsh ior "lord" and berth
"handsome". This name is used in the Mabinogion, a
collection of tales from Welsh myth, where it belongs
to a son of Maredudd. This name is sometimes used as
a Welsh form of Edward." |

Well, at the point where humanity makes up [insert

something that wasn't human. |

Soylent Green is a (very inaccurately devised) anagram
of "Chronos diet".
Not a lot of people know that. |
|
| |
In fact they're exactly the same words, apart from using completely different letters in a different order. |
|
| |
Yes, but apart from that.. |
|
| |
I believe I have found the problem, in the form of a
piglet on your sill resting under a blanket of reading
material. Swine are naturally high in animal
magnetism (see link). |

While an East-West compass would be a novelty, a
more interesting variation would be a Kata-Ana
compass. |
|
| |
Well certainly safer than a katana compass, I think if
you had a kata-ana compass, you wouldn't know if you
were coming or going, physically and temporarily. Cue
Dr Who theme music, der dum, der dum, der dum,
wheeo etc. |

BTW I heard on the news today that Toblerone has
been cleared as halal. We can all sleep in our beds
more soundly tonight. |
|
| |
... unless you're brown, made of chocolate, and divided into triangular segments. |
|
| |
Q: Do you know why they making Toblerone bars
that particular shape? |
|
| |
A: So they fit in the boxes. (sorry) |
|
| |
At the risk of giving a serious answer... |
|

Your local magnetic field might be wonky, too. I have a
magnetic compass whose idea of north varies by about 60
degrees from one end of my sofa to the other. I imagine it's
caused by currents flowing in cables in the walls & loft. |
|
| |
Very unlikely, because those currents will be AC, and besides the compass would only be affected by the near field even from a DC cable, which fades out really quickly. |
|
| |
Culprits might be large masses of ferrous metal, nearby vehicles, metal framing in furniture, or some appliances. |
|
| |
Yes, but the currents in the Xmas pud...anyway who
ever came up with name Eddy Currents? |
|
| |
Named after André-Marie Ampère, of course, known as "Andy" by most, and to his close frends and family as "Eddie". |
|
| |
I thought he was in the spacetime continuum? |
|
| |
Apart from Q, isn't everyone ... ? |
