And, it turns out, migrating birds also find their way by responding to the magnetic field of the earth. (birdnote.org)
New Mexico scientists are looking for ways to protect migrating birds from another mass die-off. (durangoherald.com)
Certainly, confusion reigns in those migrating birds and whales using the field for direction. (zetatalk.com)
But migrating birds are often rewarded with a warm place to spend the winter and an abundance of food. (nahf.org)

Biologists have identified strong responses in vertebrates ranging from fish , amphibians , reptiles , numerous birds and a diverse variety of mammals including whales , rodents , bats , cows and dogs - the last of which can be trained to find a hidden bar magnet. (discovermagazine.com)

The magnetic poles are not aligned with the geographic poles. (blogspot.com)
There are actually two pairs of magnetic poles. (blogspot.com)
The "magnetic poles" are the two positions on the Earth's surface where the magnetic field is entirely vertical. (blogspot.com)
They are not in the same place as the magnetic poles. (blogspot.com)
The magnetic poles are not at directly opposite positions on the globe. (blogspot.com)
The magnetic poles move around over time. (blogspot.com)
By this time the Earth will be in a severe wobble, caused by the daily tugging on the magnetic poles that present to the influence of Planet X - the wobble of today, exacerbated. (zetatalk.com)

To understand the effects of magnetic storms on the Earth it is important to have a basic understanding of what exactly the planet is made of. (brighthub.com)
So what exactly are magnetic storms? (brighthub.com)
Magnetic storms can affect radio signals and communications. (brighthub.com)

Since we live in mid-latitudes of the Northern Hemisphere, the environmental magnetic field in our lab dips downwards to the north at about 60 degrees from horizontal. (discovermagazine.com)
