The dynamo effect
The dynamo effect.
Electromagnetic waves, like light, do involve changes in the electric and the magnetic field. These changes propagate at the speed of light - as a wave.Electromagnetic waves, like light, do involve changes in the electric and the magnetic field.

It is a bit more complicated than just the mass, but it has nothing to do with the magnetic field
A magnetic field is caused by flowing currents, but the field lines are not directly related to the flow of electrons or other charged particles. They are simply an abstraction that tells you where the magnetic attraction is strongest, and in what direction it goes.
Caused by changes in earth's magnetic field over time, especially reversals of the magnetic poles.

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

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.
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.
