Magnetic declination

Magnetic declination or variation is the angle on the horizontal plane between magnetic north (the direction the north end of a compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole). This angle varies depending on position on the Earth's surface, and changes over time.

Somewhat more formally, Bowditch defines variation as “the angle between the magnetic and geographic meridians at any place, expressed in degrees and minutes east or west to indicate the direction of magnetic north from true north. The angle between magnetic and grid meridians is called grid magnetic angle, grid variation, or grivation.”

By convention, declination is positive when magnetic north is east of true north, and negative when it is to the west. Isogonic lines are lines on the Earth's surface along which the declination has the same constant value, and lines along which the declination is zero are called agonic lines. The lowercase Greek letter δ (delta) is frequently used as the symbol for magnetic declination.

Magnetic North (Hopesfall album)

Magnetic North is the fourth and final full-length album released by the hardcore band Hopesfall. Josh Brigham, one of the guitarists and the only founding member remaining during the recording of the album, has said: "Our music has always been spacey and heavy, and we use those roots, combined with our love of grunge-era Smashing Pumpkins, Dinosaur Jr., HUM, and Pixies, we add some bigger, heavier riffs.

"We all admire bands that can morph and change with each album, and that is what we try to do. Expect change and progression, in both songwriting and overall style, on the new album."

During the period before this album's release, the band released a new song from the album on their MySpace page each week for the ten weeks prior to the release date.

"Bird Flu" was previously released on the compilation album Trustkill Takeover Vol. 2.

Unreleased tracks

The track "Saskatchewan" was originally intended for inclusion on Magnetic North, following the album's title track, but was cut from all releases without the band consenting. When the band found out the CDs and artwork had already been manufactured. Other bonus tracks may have been planned but were not included.
