Make a pigeon B-Sick

A new wave of deterent is heaving onto our shores
  [vote for,

Anyone (and most of the rest) who experienced car sickness knows that the difference between what the eye sees, and the balance says, causes nausea.

Assuming that pigeons have a sense of balance, and a magnetic sense of direction, if there was a way to make them disgree then it might cause discomfort.

So, a magnetic field with rotating direction might severely disrupt their activities.

In humans, 1 second cycles of movement are quite effective. A magnetic field with rotation frequency of 1s would be a starting point.

A huge 3-phase motor winding type device without the rotor might do the trick. The magnetic field would not need to be strong; just similar magnitude to that of the Earth. I wonder if a complete building could be protected?

As a side experiment, all humans who have remnant sensitivity, may suffer similar nausea.

*B is the magnetic flux density, measured in Tesla

       So, a way of making the feathered rats spew from both ends ?... works for me [+]

       Kill them. Kill them all. Spare not even the children, lest the evil persist ...

       I quite like pigeons. They're smarter than some people of whom I can think.
xenzag, Jul 23 2016

       They're also partially edible.

       //They're also partially edible.   

       Linky. Remembered this from me London days.
not_morrison_rm, Jul 24 2016

       beautiful sweet clever birds.

       Yes, until they get out of hand. <link>
MaxwellBuchanan, Jul 24 2016

       // beautiful sweet clever birds. //   

       No, [po], that's parrots. Pigeons are disgusting, verminous, disease-carrying scavengers with the intellect of doorknobs.   

       Or is that Belgians ? Could be either ...

       They won more wartime medals than any other anmals
po, Jul 24 2016

       Didn't know that Belgians had won that many medals ... what for ? Chemical warfare ? That's just the normal smell of the drains ....

       If a pigeon was running for president of the USA, I would vote for it.
xenzag, Jul 24 2016

       //They won more wartime medals than any other anmals//   

       Yes, but only because the fool who decided to award medals to animals didn't have the idea until horses were no longer a major part of the military. It was pretty much a case of having to award the medals to either a pigeon or the most recent officer's lunch (sometimes both together).   

       It was also discovered, sadly too late, that a pigeon with two ounces of bronze pinned to its chest was severely impaired in the flying department.

       Worked well as body armour, though.
8th of 7, Jul 24 2016

       Not so much, though. The only difference would be a 2" diameter hole through the pigeon, as opposed to a 7.6mm hole.
MaxwellBuchanan, Jul 24 2016

       That sounds like a cue for a practical test, and possibly a song, too ... <link>
8th of 7, Jul 24 2016

       What [xenzag] said. And then some.
blissmiss, Jul 24 2016

       yes, if I had a vote.

       // 2" diameter hole through the pigeon //   

       An impromptu test using a 60mm diameter x 3mm thick brass disk, a small frozen chicken (fully defrosted) and a .30-06 FMJ round (balistically comparable to the German 7.92mm round) at a range of 50m does not result in a 60mm diameter hole through the chicken. Not unexpectedly, it simply results in no chicken whatsoever.
