How does the magnetic field help us?

Answer 1

The rocks present in earth like Basalts when cools to a certain temperature(Curie point),the earth's magnetic field is frozen into it known as fossil magnetism.It records both direction of N-S pole & the latitude of the rock.Evidence from this it has been reveled that on geologic past earth has reversed it's magnetic field many atimes.

Answer 2

The magnetic field plays a crucial role in many aspects of modern life. It is used in MRI machines for medical imaging, in electric motors and generators for converting energy, in compasses for navigation, and in various technologies like magnetic storage devices and magnetic levitation trains. It also helps protect Earth from harmful solar wind radiation.

Answer 3

From an astronomy point of view, the Van Allen belt protects the whole Earth by deflecting harmful solar radiation away from the surface. Without the magnetic field, land based life would be unable to survive.

----------------------------------------

it helps us because it gives us navigation, like with our compasses, so that means that the compasses wouldn't work without a magnetic field.

they also help the baby sea turtles to get back to the sea.

and also birds can sense it!

hope this info was good... :)

Answer 4

The Earth's magetosphere deflects most of the solar wind produced by the sun. Solar wind is mostly magnetically-charged particles that would be harmful to animals and plants if they were not blocked by the planet's magnetic field.

Answer 5

Very little. That's why you can have an MRI - Magnetic Resonance Imaging - test and experience no physical problems. But you can't have an MRI if there is _ANY_ metal on you or around you, because the induced currents would be dangerous.

Answer 6

the earths magnetic fields protect us from deadly ultraviolet rays. they deflect a majority of these waves and effectively dispose of them. mars does not have one and thus is dead because of it.

Answer 7

the earths magnetic field protects us and the earth from things such as solar winds and cosmic particles/radiation as well as solar radiation. It deflects the charged particles produced from various sources in space, however some can get in. The Northern Lights, for example, occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere. When the electrons enter the earth's upper atmosphere they will encounter atoms of oxygen and nitrogen at different altitudes and the colour of the aurora depends on which atom is struck, and the altitude of meeting. Therefore the magnetic field does not prevent all particles from entering the earths atmosphere.

Answer 8

If Earth did not have a magnetic field then all Ionically charged particles from the sun would enter earth's Ionosphere and over charge it causing global weather changes. This happens when Sun spot activity is low. The Magnetic Fields basically trap the particles and keep them far away from earth. Think of it, if you want, as an outer shield.

Answer 9

With the use of a compass, a compass is basically a relatively weak magnet, and magnets follow these rules: Opposites attract and likes repel. And using these principals and...............................

Answer 10

All you have to do is hang a magnet up by a string from the ceiling in your bedroom, and watch it for a while.
No matter which way you push it, it always points in the same direction when it calms down.
Everybody who does that in their own home finds their hanging magnets pointing the same direction.
Each one is aligning itself with the earth's magnetic field.
