Is free electricity possible?
Free energy machines do not work.
No machine can create energy out of nothing, as this would violate the law of mass-energy conservation, which is fundamental and universal.
The law of mass-energy conservation states that mass-energy can never be created or destroyed..
How can you make a magnetic field without electricity?
No, it is not possible to create magnetic waves without an electric field being present. Electric fields are created by electric charges. For instance, if you statically charged up a balloon by rubbing it on your hair, the balloon creates an electric field. Magnetic fields are created by magnets.
How is electricity generated from the Earth’s magnetic field?
To get a enough current for everybody, you must move a lot of wire through a magnetic field. We do this by spinning a coil (containing many loops of wire) quickly in a strong magnetic field. During each turn of the coil, electrons get a kick from the magnetic field, moving them along. This creates electrical current.
Does the earth produce electricity?
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet.
Can we use Earth’s magnetic field to fly?
In order to get magnet to float in the air you need reasonably strong opposing field in the direction of Earth gravity. In most places on Earth flux lines are more horizontal than vertical. … But you can’t fly really high using magnetic forces, and Earth’s magnetic field isn’t good for this.
Can the flow of electricity generate a magnetic field?
Electromagnetism is produced when an electrical current flows through a simple conductor such as a length of wire or cable, and as current passes along the whole of the conductor then a magnetic field is created along the whole of the conductor.
