Why is the earth like a magnet?
Why does the Earth have a magnetic field?
Why can’t we use earths magnetic field to produce electricity? Why are magnetic fields produced? Could the Earth's magnetic field be used to produce electrical energy? Can earth’s magnetic field be repelled by a magnet? Can earth's magnetic field be used to produce electricity? How magnetic field is produced by electric field? What is the magnetic field due to an electromagnet at a point that is not along its axis? Is it possible to use the earth's magnetic field to produce electricity? What's the difference between electric field and magnetic field? Does a magnetic field have mass? What causes electrons and protons to have a magnetic field and what are magnetic fields made of? What's the difference between a magnetic field and an electromagnetic field? Why isn't the force of a magnet limited to the magnet itself, how can it form a field? Why the magnetic field lines are normal to the surface in case of ferromagnets? What are the effects of earth's magnetic field on the atmosphere? What is the difference between electric and magnetic fields? Why does the slowly rotating planet Mercury have a magnetic field if it doesn't have a molten core? What is the relationship between a magnetic field and gravity? What is the main difference between magnetic and electric fields? What is magnetic? How are the magnetic poles of the Earth fixed? Why does a current carrying coil produce magnetic field? What is the difference between magnetic flux and magnetic field? What is the direction of induced electric field due to changing magnetic field? What is the direction of induced magnetic field due to changing electric field? Scientists say that the human body produces magnetic field so, can we harness this magnetic field and induce electrical energy just from the body? Why does a current carrying conductor produce a magnetic field around it? Which is stronger, a magnetic field or an electric field? What does a rapid change of a magnetic field induce and why? Is there any connection between gravity and magnetic fields of force?
