Q. With reference to the magnetic field of earth and other celestial bodies, consider the following statements:
- Earth’s magnetic field is generated by convection currents of the earth’s outer core.
- The moon has a dipolar magnetic field.
- The sun’s magnetic field originates from the movement of charged particles in the plasma.
Which of the statements given above is/are correct?
Answer:
Only 1 & 3
Notes: The Earth's magnetic field, or geomagnetic field, is produced by electric currents from convection in the outer core, with the North geomagnetic pole representing the south pole and the South geomagnetic pole representing the north pole. The Moon has a weak magnetic field of crustal origin, lacking a dipolar structure. Mars once had a magnetic field similar to Earth's, but it was lost due to the solidification of its outer core. current remnants are from magnetized rocks beneath the surface. The Sun's magnetic field, also bipolar, arises from the movement of charged particles in its plasma.
