    Question

    _______ creates a magnetic field around the earth.

    1. Crust
    2. Inner core
    3. Mantle
    4. Outer core

    hintHint:

    The magnetic field around the earth's crust is due to the outer mantle.

    The correct answer is: Outer core

      • The outer core which has convection converts the kinetic energy created by heat into electrical and magnetic energy.
      • The liquid around the core has ions that get leveled up on solidification.
      • So the outer core is responsible for the magnetic field around the earth's crust.
