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.

Why is studying bacteria and animals who use magnetic fields to navigate useful?
Magnetoception is a type of navigation used by some animals. It is navigation that uses electromagnetic fields, and has been observed in bacteria. It is useful because scientists might be able to come up with different types of navigation.
Can 'who' be applied to animals?
In general, who is reserved for humans. Which might fit as an alternative for who when applied to animals.
Why do you need animals on earth?
We don't need animals, they just naturally came into our world just like humans.
What is cause background extinction?
It is the fate of most living things eventually to go extinct. standard commonplace rate of extinction not associated with a mass extinction.
What is a person who assists in handling animals?
A person that assists in handling animals can be called a groom if they work with horses. A person who works with zoo animals might be called a trainer, zookeeper, or handler. A person who raises animals for food might be called a rancher or dairy farmer.
Why would we not expect magnetic fields on the moon or mercury?
You might, but that would be wrong! Mercury has a strong magnetic field.

Does a cold planet's core have magnetic fields?
It MIGHT have. If the SURFACE of the planet is cold, its interior can still be liquid, for billions of years - allowing the currents that cause the magnetic field. Note, for example, that Jupiter has considerable magnetic fields.
Are humans evil to animals and the earth?
it depends. if its a person who hates animals and earth then they might be mean to them but if they love earth and animals then thwy might not.
How does the sun's magnetic field affect the solar system?
The sun's magnetic field is what causes the phenomenon known as sunspots. Magnetic fields also affect the earth's weather. Sunspots are a cyclical occurrence that cause solar flares, magnetic activity that affects the earth.
What causes Earth's magnetic field to have the shape it does?
As you might already know, a magnet is the most powerful at it's ends. So what the inner core of the Earth's magnetic field does is that it surround the Earth. Thank you.
Can Magnets still attract underwater?
Yes, water has almost no effect on magnetic fields. (though electromagnets might have a shortcircut)
What if earth's magnetic field did not occasionally reverse polarity?
We expect Earth would still have a magnetic field during a reversal, but it would be weaker than normal with multiple magnetic poles. Radio communication would deteriorate, navigation by magnetic compass would be difficult and migratory animals might have problems. Many migratory animals use the geomagnetic field to orient themselves. However, even if Earth's magnetic field began a reversal, it would still take several thousand years to complete a reversal.
How does the earths magnetic field affect animals?
For most animals, not at all. There was a theory that pigeons might be able to detect it, but that seems to be false.
Which direction does magnetic fields flow?
I think it is a mistake to refer to magnetic field 'flowing. Magnetic fields just are, they can change, and these disturbances might move in space, but the field itself does not flow. That being said, and assuming you meant to ask in which direction a magnetic field points the answer is that a magnetic field points towards the south pole of a magnet and away from the north pole. A magnetic field cannot be divergent (i.e. there are no sources) and any field line must be closed.
Does the earth rotation effect the sun in any way?
If there is any effect at all, it would need to be a very tiny one. The only way that the Earth's rotation might affect the Sun would be in the way the Earth's rotation generates Earth's magnetic field. Our magnetic field affects the way that coronal mass ejections, huge bubbles of ionized gas from the Sun, behave when they get close. But the Sun has a magnetic field of its own, much stronger than the Earth's field, and it is unlikely that the Earth's magnetic field would affect the Sun or the Sun's magnetic field in more than a minuscule fashion.
If there are ice fields on other planets then can ice caves form just like on earth?
They might. Just remember, the only (water) ice fields we know of are on satellites, not planets.
