Right Hand Rule: Magnetic Field Direction from Current-Carrying Wire

Click For Summary
SUMMARY

The discussion focuses on determining the direction of the magnetic field generated by a vertical wire carrying a 3 amp current. Utilizing the right-hand rule for magnetic fields, the magnetic field direction is established as being perpendicular to the current flow. Specifically, at a point 1.2 meters away from the wire and 20 degrees north of east, the magnetic field is directed towards the south. This conclusion is supported by the principles outlined in Right Hand Rule #2.

PREREQUISITES
  • Understanding of electromagnetic principles
  • Familiarity with the right-hand rule for magnetic fields
  • Basic knowledge of current flow in conductors
  • Ability to visualize three-dimensional vectors
NEXT STEPS
  • Study the application of the right-hand rule in various electromagnetic scenarios
  • Explore the effects of varying current strengths on magnetic field direction
  • Learn about the Biot-Savart Law for calculating magnetic fields
  • Investigate the relationship between magnetic fields and electric currents in different configurations
USEFUL FOR

Physics students, electrical engineers, and educators looking to deepen their understanding of magnetic fields generated by current-carrying conductors.

A vertical wire carries an upward 3 amp current. you are 1.2 m from the wire in a direction 20 deg north of east. You experience a magnetic field ( due to the wire) that is directed in what direction? Yes, you do use the right hand rule, but what direction does the right hand rule tell you?
