Many (but not all) birds, fish,, insects, etc. have the ability to sense earth's magnetic field. They use this ability for navigation purposes, much as we use magnetic compases.
They use the Earth's magnetic field to determine direction and position.
There are theories around that some birds can actually detect magnetic fields, which they use to navigate on long migrations.
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.
no ...YES!
Swallows use both the Earth's magnetism and the angle of the sun to find their way to the tropics when they migrate. They may also use topographic features and their sense of smell to find their way to the tropics for the winter.
We can use iron filings, a magnetic compass, or a Hall probe to find the shape of a magnetic field. Iron filings line up along magnetic field lines, a magnetic compass shows the direction of the field, and a Hall probe can measure the strength of the magnetic field at different points.
To find the direction of the magnetic field, you can use a compass or a magnetic needle. The needle will align itself with the magnetic field lines, pointing towards the direction of the field.
To reduce the strength of a magnetic field, you can increase the distance between the magnet and the object affected by the field, use a material that can shield or redirect magnetic fields (like mu-metal), or use a magnetic field cancellation system that generates an opposing magnetic field to nullify the original field.
All I know for sure is that when a strong magnet is near my parakeet's head, its pupils will shrink.
You can show that the Earth has a magnetic field by looking at a magnetic compass.The north end of the compass points to the north magnetic pole, and does so everywhere on Earth. It does this by aligning itself to the Earth's magnetic field. If there weren't a magnetic field, then a compass needle would not point to any consistent direction.See related links.
The Earth's magnetic field protects the planet from harmful solar winds and cosmic radiation by creating a magnetosphere. This magnetosphere also guides the migration patterns of animals, such as birds and sea turtles, which use the Earth's magnetic field for navigation. Additionally, the auroras, also known as the Northern and Southern Lights, are caused by charged particles from the sun interacting with the Earth's magnetic field near the poles.
