The "North Star" or "Polaris" is within about 1/2 degree of the North Celestial Pole.
The result is that for anybody in the northern Hemisphere, it appears at an angle above
the northern horizon that's within 1/2 degree of their latitude.
Here is the angle as seen from Harrisburg:

Instruments such as a sextant or a quadrant can be used to determine the altitude of the North Star. By measuring the angle between the North Star and the horizon, navigators can determine their latitude.
The point on the horizon that is due west has an altitude of zero and an azimuth of 270 degrees.
As you move north in the northern hemisphere, the altitude of Polaris, also known as the North Star, increases. Polaris is situated almost directly above the North Pole, so its altitude corresponds closely to your latitude. At the North Pole, Polaris is at the zenith (90 degrees), while at the equator, it is on the horizon (0 degrees). Therefore, as you travel northward, you will see Polaris rising higher in the sky.

Zero. (It's on the horizon.)

The idea is there, but a couple of important terms are swapped.The altitude of the North Star above the northern horizon is approximately equal tothe observer's north latitude.
The altitude of the North Star will not change from any point on Earth. However, the declination changes depending upon where you are and when - It is less than 90 degrees.
Northville, MI is at 42 degrees, 26 minutes North. The altitude of the North Star is between 42 degrees and 43 degrees, depending on the time. (Polaris isn't exactly at the North Pole; it is about 1/2 degree off.)
If you are at the North Pole, you'll see the star Polaris near the zenit (altitude almost 90 degrees).
The altitude of polaris for an observer is always the same as your latitude so it would be 64oN
The device used to determine the altitude of the North Star (Polaris) is called an astrolabe. An astrolabe is an ancient astronomical instrument that allows users to measure the angle of celestial objects above the horizon. By aligning the astrolabe with Polaris, one can determine their latitude based on the altitude of the star. This technique has been used for navigation and understanding one's position on Earth.
Azimuth is the horizontal angular distance measured clockwise from true north, while altitude is the vertical angular distance above the horizon. Together, these coordinates help locate a star's position in the sky.
Yes. Two thousand years ago, the current Polaris was not the North Star. By the end of the 21st Century it will not be above the North Pole.

As you move south in the Northern Hemisphere, the altitude of Polaris decreases. Polaris, or the North Star, is located almost directly above the North Pole at an altitude of about 90 degrees. As you travel southward, its angle above the horizon diminishes, reaching zero degrees at the equator, where it is no longer visible.
