The direction of the lines tells us whether there is attraction or repulsion, and the spacing of the lines is a measure of the strength of the magnetic field. The more crowded the lines the stronger the field.
magnetic variation
There is no relationship between GPS (Global Positioning System) and magnetic fields. The GPS system is based on a network of satellites that provide a reference datum that is based on position, regardless of magnetic field.
Magnetic declination
Zero.
There is no such thing as a purely magnetic wave. The wave aspect of an electromagnetic wave comes from the oscillations between electric and magnetic fields.
How can I go by finding magnetic and Non-magnetic in my home. nonsense

There are no purely magnetic waves.
About Midway between the earth's magnetic poles.
magnetic tapes are cheaper
Since the Earth's magnetic poles are not located at the geographic poles, a magnetic compass doesn't point to 'true' (geographic) north. The DIFFERENCE angle between magnetic north and true north is the magnetic variation or declination where you are. It changes for different locations.
What are the differences between electrical and magnetic circuit.
People don't migrate. Animals migrate. So, there are no patterns between humans and animals.
Magnetic force is the force exerted between magnetic poles, producing magnetization of force, either of attraction or of repulsion.
