The discussion revolves around the relationship between the direction of current in a wire and the resulting orientation of the magnetic field. The original poster describes a scenario where the current flows from east to west and seeks to understand the magnetic field direction below the wire.
There is an ongoing exploration of the correct application of the right-hand rule and the implications of the current's direction. Some participants are attempting to reconcile their findings with the expected answer, while others are providing insights into the orientation of the magnetic field relative to the wire and the plane of the paper.
Participants are addressing potential ambiguities regarding the orientation of the paper and the definitions of directions in a three-dimensional context. The original poster expresses difficulty in aligning their understanding of the magnetic field direction with the expected outcome.
East to West defines a line, what plane do you speak about?Suyash Singh said:
Plane of the paper?Suyash Singh said:
The paper can be horizontal, vertical, or can stand in any direction.cnh1995 said:
the plane of paper since north south east west are in plane of paper.ehild said:
Your fingers come out of the paper beside the wire or above it. Just under the wire the fingers stand in the North-West direction, and having short fingers, the tips would point to the South. The green vector represents the direction of the magnetic field under the wire.Suyash Singh said:
