What truly causes Earth's magnetic field? The Earth's magnetism is a fascinating topic that delves into the principles of magnetism and matter, crucial for NEET and JEE aspirants. Understanding the origin of the Earth's magnetic field involves concepts like the dynamo theory, which describes how the motion of molten iron in the outer core generates magnetic fields. This knowledge is vital not only in physics but also in understanding navigation, geology, and the behavior of solar winds. Dive deep into this topic and prepare to ace your exams! 🎓 #Magnetism #EarthScience #Class12 #NEET #JEE #Physics #ExamPrep #ScienceQuiz

Question: What is the primary mechanism responsible for Earth's magnetic field?
A) Permanent magnets in the crust
B) Electric currents in the atmosphere
C) Movement of molten iron in the outer core
D) Magnetic minerals in the soil

Answer: C

Explanation: The primary mechanism behind Earth's magnetic field is the movement of molten iron in the outer core, which creates electric currents that generate magnetic fields through the dynamo effect.
