The conducting wire wrapped around the compass is energized creating a magnetic field that counteracts the effects of the Earth's magnetic field and changes the direction of the compass needle.
No they are caused by changes in magnetic and electrical fields. When a magnetic field changes it causes an electric field that is perpendicular to it. And vice versa a changing electric field causes a perpendicular magnetic field. These changing fields propagate outwards at the speed of light and are what is meant by an electromagnetic wave.
Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other.Yes.

answer
Uniform magnetic field depends on the position of its surrounding. A non uniform magnetic field changes its position from one place to another.
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.

Earth's magnetic field has no effect on its axial tilt.

Capacitive reactance is an opposition to changes in voltage across an element. This resistance is usually caused by a magnetic field.
A magnetic field
The magnitude of the magnetic field is decreased
From changes in its magnetic field, assuming that the magnetic field rotates with the core.
