I ordered a couple of horn drivers yesterday from MCM. One with a 30 oz. and the other a 50 oz. magnet. Sales fella said they could not ship by air because MCM doesn't have a HAZMAT endorsement.
What do you suppose a NV400 with a Black Widow would do in the cargo hold of a big bird? Make north point south? |

| May seem funny, but when I once hauled an amp in the back of my buddies van - it screwed with the compass readout in the mirror - it was off about 45 degrees all the time and when we removed the amp, it was fine???????? |

Had a band rehersal in the living room once where the guitar players Twin/w-JBL's was just inches away from the screen of my TV and later that night,the color was all messed up across the bottom of the screen for the first few min's after it was turned on. It fixed it's self, but we never put the guitar player in front of the TV again!! LOL

| When I drove for Emery Airfreight, I had JBL as an account. Gee, all those speakers! Anyway, magnetized speakers were, at one time, listed as haz-mat for air carriers.(I think it was pilot notification only, not pilot accessibility) However, that was changed, oh maybe 3 years ago. Small shipments were loaded aboard the plane, without restriction, but I dont recall any restrictions on larger shipments. |

| I mistakenly set a guitar speaker on top of my television a number of years ago and, while the picture improved after removing the speaker, it was never the same (this was before the auto-degaussing days) |

My uncle was a US Naval engineer, who on a dare, created a cylindrical magnet. Instead of the poles at either end, the opposing poles were inside and outside. It appeared to be a high quality metal tube about a 12-15" long, 4-5 inches OD with walls about 1-1/2" thick.
If you took it near a TV set you could invert the picture. HE asked us not to do that. IT would also stop a watch at 5 feet away any closer and it would never work again.
I have seen magnets that will pick up dollar bills because of the metal in the ink.

I picked up a little 3-pack of neodymium disc magnets at the hardware store for a project. Silly little things, 1/8" X 3/4" diam. After the extreme effort of prying them apart (you can't...you've got to slide them apart) I nearly lost a finger when they jumped back together.
I gained a healthy respect for the havoc potential within these little buggers.
If someone were to tell me that there are odd hazards related to shipping/handling of magnets, at least now I will give a fair hearing to their case. (Then I'll deride them). |

magnets are so interesting. as kids, my brother and I played with little round magnets he brought back from the Allen Bradley Co. we thought they had magic.
of course as an adult I understand magnets better.
they do have a bit of mystery for me. I cannot figure out why I have attraction for my ex wife. she was full of magnetism. |

There is one company (the name escapes me right now) that specializes in neodymium magnets. Their website is chock full of warnings, along with the admission that their magnets are packed and shipped by carefully-trained engineers (not minimum-wage immigrants) to avoid problems. Neo magnets have enough attractive power to break bones and crush fingers if they're mis-handled!
"Caviat asterior", as they say.  |

| Well, I want some kinda electro magnet that I can hide in the bushes by the street, and whenever one of those dumb kids comes down the street with his stereo boomin' and bumpin', I could flip a switch and blow his 18" woofers to Hades! |

gauss number is the key here..."magnatized materials must not be loaded in such a position that they will have a significant effect on the direct-read magnetic compass or on the master compass detector units. The minimum stowage distance varies from 5 feet for those materials which just meet the threshold level of the magnatized material defination (.002 gauss) to 15 feet for the materials which posses the maximum field strength (.00525 gauss) field strenght"...
That is from my company's Flight Operations Manual and based on the rules of HMR 175 (hazmat regs). I don't know if there is direct relation between gauss and magnet weight but if you know the gauss value of the speaker, you can determine whether or not you can expect over-night service.
Over-night freight generally flows; courier truck-small aircraft-large aircraft-sorting facility and back in the reverse order. The large aircraft shouldn't have to much trouble with compass/INS distance but us puddle jumpers do
