SUMMARY

The term "horizontally north" refers to a physical direction that is parallel to the ground and oriented towards the geographic north. In the context of electricity and magnetism, when a wire carries a current "horizontally to the north," it indicates that the current flows in a straight line parallel to the Earth's surface, directed towards the north. This terminology is essential for accurately describing the orientation of currents and movements in physics problems.

PREREQUISITES
  • Understanding of basic physics concepts related to electricity and magnetism.
  • Familiarity with geographic directions and their implications in physical contexts.
  • Knowledge of vector representation in physics.
  • Basic comprehension of current flow in electrical circuits.
NEXT STEPS
  • Study the principles of vector representation in physics.
  • Learn about the implications of current direction in electromagnetic fields.
  • Explore the relationship between geographic directions and physical movement in physics.
  • Review problems involving current flow in various orientations, particularly in electricity and magnetism contexts.
USEFUL FOR

Students of physics, particularly those studying electricity and magnetism, educators looking for clear explanations of directional terminology, and anyone interested in the practical applications of current flow in physical systems.

Homework Statement


I am in Intermediate Electricity and Magnetism, and am working on review problems.
I have a potentially very silly question:
What physical direction is "horizontally north" (and similarly "horizontally south")?
This seems like a counter-intuitive description to me (90 degrees?) and yet I keep encountering it, for example in the context such as "the wire carries a current horizontally to the south," "slides horizontally to the north." (these two statements NOT part of the same problem)
Any insight much appreciated!

A current that is horizontally north would be a current that is horizontal (parallel to the ground) and also toward the north.
