magnetic dip
Học thuậtThân thiện
Definition
- Noun:
- The angle of magnetic inclination: "magnetic dip" is the angle formed between a freely suspended magnetic needle and the horizontal plane. It indicates the vertical component of the Earth's magnetic field at a given location.
Usage
- "Magnetic dip" is a technical term used primarily in physics, geology, navigation, and surveying to describe the vertical tilt of the Earth's magnetic field lines.
- It is measured using an instrument called a dip circle or inclinometer.
- The value of the magnetic dip varies from 0 degrees at the magnetic equator to 90 degrees at the magnetic poles.
Examples
- Noun:
- The magnetic dip at this latitude is approximately 60 degrees.
- Sailors in the 18th century used knowledge of magnetic dip for navigation.
- Scientists measure the magnetic dip to study changes in the Earth's magnetic field.
Advanced Usage
- "Angle of dip": A synonymous term for magnetic dip.
- The angle of dip increases as you move toward the magnetic poles.
- "Inclination": Often used interchangeably with "magnetic dip" in geophysics.
- The magnetic inclination in this region is very steep.
Variants and Related Words
- Dip circle (n): An instrument for measuring magnetic dip.
- He calibrated the dip circle before taking measurements.
- Magnetic inclination (n): Another term for magnetic dip.
- The map showed lines of equal magnetic inclination.
- Isoclinic line (n): A line on a map connecting points of equal magnetic dip.
- The isoclinic line for 70 degrees passes through this area.
Synonyms
- Angle of dip: The angle a magnetic needle makes with the horizontal.
- Magnetic inclination: The inclination of the Earth's magnetic field lines from the horizontal.
Related Phrases
