Yes, the Earth has a magnetic field.
lead is an inert metal and can not be magnetised
An electromagnet must have an electric current passing through its coils to generate a magnetic field. The magnetic field is created as the electric current causes the alignment of the magnetic domains within the core material of the electromagnet, creating a magnetic field around the coil.
Electromagnetic Waves.
When the magnetic fields of two or more magnets overlap, they can either reinforce each other, resulting in a stronger magnetic field in the area of overlap, or they can cancel each other out, weakening the magnetic field. This is due to the interaction of the magnetic field lines produced by each magnet.
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.
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.
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
Yes, the Earth has a magnetic field that surrounds it called the magnetosphere. This field is generated by the movement of molten iron in the Earth's outer core and helps protect the planet from harmful solar radiation.
