1. Having the same magnetic inclination or dip; relating to points on Earth's surface where the magnetic needle makes the same angle with the horizontal plane.
Usage: technical; geophysics

1. A line on a map connecting points of equal magnetic inclination.
Usage: technical; geophysics

Examples

• Isoclinic lines on a magnetic map show regions where the compass needle dips at the same angle.
• Navigators use isoclinic charts to account for magnetic inclination variations across different latitudes.
• The isoclinic for 45 degrees passes through several continents.
• Geophysicists study isoclinic patterns to understand Earth's magnetic field structure.
• An isoclinic line connects all locations with identical magnetic dip angles.
