FAQs on Earth's Magnetism Video Lecture - Physics for JAMB
| 1. What is Earth's magnetism? |  |
Ans. Earth's magnetism refers to the magnetic field generated by the Earth due to the movement of molten iron in its outer core. It acts like a giant bar magnet with a north and south pole and plays a crucial role in various natural phenomena.
| 2. How is Earth's magnetic field generated? | |
Ans. Earth's magnetic field is generated by the movement of molten iron in its outer core. This movement, known as convection, creates electric currents, which in turn generate the magnetic field.
| 3. What is the significance of Earth's magnetism? | |
Ans. Earth's magnetism is significant for several reasons. It helps protect the planet from harmful solar radiation, guides animals during migration, and aids in navigation for humans. It also plays a crucial role in the formation of auroras and affects the behavior of compass needles.
| 4. How does Earth's magnetic field affect compasses? | |
Ans. Earth's magnetic field aligns the needle of a compass with the North and South poles. The compass needle points towards the Earth's magnetic North, which is slightly different from the geographic North. This enables navigation and helps people find their direction.
| 5. Can Earth's magnetic field change over time? | |
Ans. Yes, Earth's magnetic field can change over time. The magnetic poles can slowly move, and at times, even reverse their positions. This phenomenon, known as geomagnetic reversal, has occurred multiple times throughout Earth's history. Scientists study these changes to better understand the planet's geology and magnetic processes.
