though curiously, our brains do contain magnetite, the mineral thought to aid other animals' brains in detecting the field.)
There are many animals that are thought to use magnetic fields in their navigation. Birds Tortoises/Turtles Dolphins Probably something they use without actually thinking about it.
No, Ceres does not have a magnetic field around it.
Earth's magnetic field is thought to be a result of the movement of liquid iron and nickel in the outer core of the Earth, creating a dynamo effect. This movement generates electric currents that produce the magnetic field surrounding our planet.
There are many animals that make a buzzing sound. The gnats, flies, all types of beetles and bees. These really are not thought of as animals, rather they are thought of as insects.
Yes, Triton, the largest moon of Neptune, does have a weak magnetic field. It is thought to be the result of the moon's subsurface ocean interacting with its icy shell and the magnetic field of Neptune.
Because it is far too small to have any effect. The Earth's magnetic field is thought to be generated thousands of miles underground by moving rivers of iron.
Im not sure if this is the correct answer but its my thought that for magnetism to work there must be a magnetic field. Not all celestial beings have a magnetic field allowing for a magnetic attraction therefore magnetism cannot be the answer to the gravitational problem of space flight though it is also my thought that a series of motor driven gyroscopes might hold an answer.
The owner wanted to preserve the bodies and thought animals were alive in the after life
The thought that animals too have rights, and are not to be killed at a whim.
There is some navigation accomplished by organisms that base their ability to do this kind of navigation on a small "compass" of iron oxide. It is this that permits them to sense magnetic fields. But most of animal navigation like this is accomplished by specialized biochemical structures that carry out ion transfers whose outcomes are influenced by magnetic fields. The study of the actual mechanism, the neurobiology, by which animals can sense changes in magnetic fields continues. And the biochemistry is complex. A link is provided to get you started on this topic. It takes a fair amount of chemistry and even more biochemistry to understand the actual mechanism themselves. And they're still not clearly understood. There's plenty of work to be done. A doctoral candidate who wishes to pursure the degree by working on animal navigation and magnetic sensing has some options open to him.
The Earth's magnetic field is generated in its outer core, which is a layer of molten iron and nickel. The movement of this liquid metal is thought to create electrical currents, which in turn generate the magnetic field.
