Yes, the Earth has a magnetic field.
lead is an inert metal and can not be magnetised
It sticks
Electromagnetic Waves.
Eddy current loss in Transformers is because of the eddy currents formed in the body of the magnetic core.Whenever a conductor(iron core) exposed to a changing magnetic field a magnetc field produced in the body of the magnetic core.That induce a circulating current in it.Which is called eddy current.In the case transformer it is loss.But it is useful in other purposes.
Earth and seeds, good luck
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
The Earth's Magnetic field.
No, there is a magnetic field round the Earth.
The Earth's magnetic field is the result of electrical currents flowing in the earth.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
Earth's gravitational field extends to infinity. No matter how far you are from the earth, It's gravitational field will always pull you towards it. However, the further you are from the earth, the weaker that force will be.
The Earth's magnetic field is probably caused by convective currents in Earth's interior.
