Earth magnetism by Shivam Dhawal

2. Earth’s magnetism
Importance of Earth’s magnetic Field:
1. Prevents from Sun’s instanced Electromagnetic
Radiation(heat, UV, X-rays etc.)
2. Vanish the celestial objects like meteor.
3. Led to Rotate and revolve to natural Satellites like
moon.
4. Supports to working of artificial Satellites for
communication, globalization etc.
5. Maintaining the suitable Environmental conditions
on Earth.

3. OriginOfMagnetismofEarth
The generation on Earth’s magnetism is controversial for the todays Scientists and researches were going on but
following were few regarded concepts:
1. Due to Suns Electromagnetism.
2. Radiation.
3. Convection(outer core).
4. Conduction.
5. Rotation and revolution of Earth.
NOTE: This concepts are derived on the reverse experimentation on Earth Electromagnetism.
These results are given on the bases of the following studies:
1. Meteors.
2. Seismic waves.
3. Gravitation and magnetic field variation.
4. Aurora Study.
5. Mechanical methods.

4. Solar Winds: 1. Energized charged Particle in Plasma State.
2. Flowing outward from sun
3. At speed as high as 900 km/s @ 1 million degree Celsius.
4. Caused by hot Solar corona.

5. Earth’s Magnetosphere:
the region surrounding the earth or another astronomical body in which its magnetic field is the
predominant effective magnetic field.
Magnetosphere
magnetopause
Bow Shock
Polar cusp
Plasma Sheet
Neutral Point
Magneto tail
Plasmasphere
North Lobe
South Lobe

6. Facts about Earth magnetism.
• Angle b/w magnetic and
geographic poles: 11.5˚.
• High Solar Prominence
may cause earth magnetism
distortion.
• geomagnetic reversal.
• Highest at poles and lowest
at equator.
• Inside earth South pole is
nearest to north pole and
vice versa.
