The imaginary line that circles the earth at 23.5o N is the Tropic of Cancer. This line is parallel with the equator.

The Tropic of Cancer is the imaginary line that circles the Earth at 23.5°N latitude. It marks the northernmost point where the sun appears directly overhead at noon during summer solstice.
The Arctic Circle is a line of latitude. As of 2012, it is approximately 66° 33' 44" N latitude.
" 30° N " is a statement of latitude. All the points on Earth that have that latitude form a parallel of constant latitude, or a 'line' if you will.
Latitude 66.5 N represents the Arctic Circle, which is an imaginary line located 66.5 degrees north of the Equator. This latitude marks the southern boundary of the Arctic region, where during the summer solstice, the sun remains visible for 24 hours due to the tilt of the Earth's axis.

Latitude is measured north or south from a planet's equator line, an imaginary great-circle circumference line consisting of all points equidistant from the two poles. The equator is the zero-degree (0o) latitude line. The geographic poles will be, by definition, points at 90o N latitude and 90o S latitide.
The imaginary line located at 66.5 degrees south latitude is called the Antarctic Circle. This is the southernmost latitude at which the sun can remain continuously above or below the horizon for 24 hours during the summer and winter solstices, respectively. It marks the boundary of the Antarctic region.
