My younger brother is doing a project this weekend and he needs some information on what materials can stop a magnetic field. which sounds much better than a project on armpits. (his original choice) please help.posting links would help a lot too. (:
Nothing will completely stop a magnetic field. Ferromagnetic metals can partly shield against the effects, e.g. mu-metal is often used as a shield. .I forgot. Superconductors will expel magnetic field lines from the body of the material, so perhaps a superconducting box could be used as a magnetic shield
Yes, call the animal shelter so that trained professionals can help try to save them. Go away and leave the area and babies quiet, and let the mother come back if she tries, so that animal control can relocate the whole family group. Their chances are much better that way.
I love that electric solution, but it seems elaborate and time consuming. I'm a chemical warfare kinda guy. Get a pack of hotdogs. Open them and let them sit out for about an hour. Then stab them all with a fork until their well dotted. Then submerge them completely in antifreeze for a few hours. Leave the hot dogs where they'll eat them.preferably away from where real pets might get to them. They will likely be dead in a few days, but you may need profession removal if they decide to die under your deck. Alternative is pepper spraying them, but that will probably just make them mad.
A magnetic field can't be blocked, but it can be canceled by another magnetic field. Ferromagnetic materials, like soft iron, generate a magnetic field which does so. This action can be represented by lines of magnetic flux. In effect, the lines of flux find an easier path in the ferromagnetic material. That is one way to explain why there is no magnetic flux inside an iron box, even when a magnet is held near the outside of the box. Actually, the iron box generates a magnetic field which is equal and opposite the field that would be present inside the box if the box weren't there.
