The Sun's core.
An electric current passing through a conductor generates a magnetic field.

yes it can
it's not
To start if we didnt have a magnetic field we would be fried by the suns radiation. The northern lights are evidence that we have a magnetic field surrounding earth.
The magnetic field for an electromagnet is created by the flow of electric current through a coil of wire, which generates a magnetic field around the coil.
Electric and magnetic fields are perpendicular to each other in electromagnetic waves. A change in the electric field generates a magnetic field, and a change in the magnetic field generates an electric field. They support each other and travel together in a wave-like fashion.
Yes, a moving charge can produce a magnetic field as it generates a magnetic field due to its motion. This phenomenon is described by Ampere's law in electromagnetism.
Earth has a magnetic field because of the movement of molten iron and nickel in its outer core. This movement generates electric currents, which in turn create a magnetic field around the planet.
An electron is a spinning particle that creates a magnetic field. The spinning motion of the electron generates a magnetic dipole moment, resulting in the creation of a magnetic field around the electron.
Yes, that is the whole idea of an electromagnetic waves. A changing electric field generates a changing magnetic field; a changing magnetic field generates a changing electric field; and the two of them propagate as a wave at the speed of light.
