How is earths magnetic field used by people and animals?
People use Earth's magnetic field for navigation, such as in compasses to find direction. Animals, like birds and fish, can sense Earth's magnetic field to navigate during migration or find their way in the ocean.
What animals follow the earth's magnetic field?
Almost all creatures sense magnetic field except us, human.
How does the earths magnetic field affect animals?
Animals such as birds, sea turtles, and bees use the Earth's magnetic field for orientation and navigation during migration or foraging. The magnetic field helps them find their way and maintain their sense of direction over long distances. Disruptions in the Earth's magnetic field, such as geomagnetic storms, can disorient these animals and impact their behavior.
Which Human sense organ is sensitive to magnetic field?
touch
Does the earths magnetic field help guide certain birds?
Yes, Birds are believed as well as other animals to have an innate sense of direction, or a "built-in compass" by earth's magnetic field. Concerns have arisen about electromagnetic interference with their internal compasses and our radio and other electromagnetic transmissions, such as the theory of why Bees are seemingly disappearing.
Is magnetic a type of energy?
It takes some energy to build up a magnetic field; when the magnetic field collapses, the same amount energy is released again. So, it makes sense to consider that somehow, energy is stored in the magnetic field.
Is earth an electromagnet?
a part of the earths structure causes it to act like an electromagnet

Pigeons have multiple-domain magnetite magnets within their skulls that are connected through a large number of nerves to the pigeon's brain How does this aid the pigeon in navigation?
The presence of magnetite magnets in their skulls helps pigeons sense Earth's magnetic field, allowing them to navigate accurately. This information, processed by their brains through the connected nerves, acts as a built-in compass that guides them during migration or when exploring new areas.
What would happen if field lines crossed?
Then, at some point, the field would go into two directions simultaneously, which doesn't make much sense. The magnetic field lines form continuous closed loops.The tangent to the field line at a point represent the direction of the net magnetic field B,at that point.The magnetic field lines do not intersect,if they did, the direction of the magnetic field would not be unique at the point of intersection.
How does distance affect magnetic fields?
Distance affects magnetic fields in the sense that the strength of the magnetic field decreases as the distance from the source increases. This relationship follows an inverse square law, meaning that the magnetic field strength reduces rapidly as distance increases. As a result, the influence and impact of a magnetic field weaken with greater distance from its source.
What is one navigation guide for animals migration?
One navigation guide for animals during migration is the earths magnetic field. Many animals are sensitive to the magnetic fields and use them in navigation. The invention of cellphones with their towers are beginning to cause issues with some migrations due to the altered magnetic field around them.
