### Question 19**What is not true about the Earth's magnetic field?**- ○ It has always pointed in one direction.- ○ It is produced by moving electric charges.- ○ It is responsible for the aurora borealis and aurora australis.- ○ It traps particles in the Earth's magnetosphere.

The Earth's magnetic field is produced by the electric currents in the molten metallic core and these currents are formed by the ionic motion of iron and nickel ( charged particles). The Aurora borealis and aurora australis are natural phenomenon when charged particles from the solar wind got trapped in the earth's magnetic field. thus, the false statement is Earth's magnetic field always pointing in the one direction. because, the direction of earth's magnetic field continuously changes as the changes in the convection currents produced in the core.
