How can you show that a given bar is a magnet?
The following two methods are really the same idea:1). Test against a known magnet. Observe whether there is an attraction or repulsion between them.2). Hang the bar by a string from its mid-point. Observe whether it shows a tendency to align itself in a preferred direction.Another method:3). Observe whether the bar picks up paper clips. ---- If you have two bars and are told that one of them is a magnet but the other is not, and you are not allowed to use any other metal, string, etc. to determine which is which, see which one is attracted to the middle of the other bar. That one's the magnet.

What did Aristotle observe that convinced him that the earth is a sphere?
nothing
When the solar wind collides with the earth's magnetic field what do we observe?
The Aurora's.Northern Hemisphere - Aurora borealisSouthern Hemisphere - Australis borealis
What happens in earth interior to produce earths magnetic field describe the layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.

How was the first man made magnet made?
Hans Oersted, a Dane, was the first to observe the magnetic effect of a current carrying conductor - about 1819.
What are magnetic field lines and how do they show the strength of a magnet?
Magnetic fields are bascially lines of force caused by magnetic poles. It is invisible, but you can track how the field lines are formed doing a small experiment. Spread some iron fillings on a tray. Then bring a magnet up close to the iron fillings but not too close. You can observe that the iron fillings move into the field lines of the magnet that you brought up close. That's a miniature of a magnetic field. The earth's magnetic field is much bigger.
How is the angle of magnetic declination measured?
You need to determine the geographic north, for example by observing sunrise and sunset; by observing the stars; or by using a compass that reacts to Earth's rotation (a gyrocompass). Then you observe where the needle of a magnetic compass points. Finally, you measure the angular difference between the two.
Why does a magnetic field create around the earth when the earth spins on its axis?
The Earth spins on its axis purely because of the conservation of momentum. The material of which it was formed had a net spin and this is what we observe. The magnetic field is caused by the flow of liquid material not far beneath the crust. This flow generates an electrical current, and this in turn produces the magnetic field. This current flows approximately parallel to the Equator.

Why does a magnet attract a plastic car?
Either there is some ferromagnetic material in it, or given a large enough magnetic field, some plastics are paramagnetic, and are weakly attracted to magnetic fields. If this is something you have observed, however, it's probably due to some metal in the car, as the magnets required to observe paramagnetism are truly huge.
Do I add or subtract the declination constant for Dallas Texas to find true north?
You don't need to worry about declination to find true north; just observe the north star, and that's it. Perhaps you're starting with a magnetic compass and want to find true north? The correction factor is "magnetic variation", or "magvar", and this is printed on your charts.
What is observe in Spanish?
To observe is "observar."
