Right Hand Rule Associated Question

Click For Summary
SUMMARY

The discussion centers on the interaction between two current-carrying wires, specifically addressing the phenomenon of magnetic repulsion. The correct answer to the posed question is that the wires will repel each other due to the direction of the currents. The right-hand rule is employed to determine the magnetic field orientation and the resulting forces acting on the wires. Understanding the magnetic fields generated by each wire is crucial for grasping the underlying principles of electromagnetic interactions.

PREREQUISITES
  • Understanding of the right-hand rule in electromagnetism
  • Familiarity with magnetic fields and forces
  • Knowledge of current direction in wires
  • Basic principles of electromagnetism
NEXT STEPS
  • Study the right-hand rule for magnetic fields in detail
  • Explore the principles of electromagnetic force between parallel wires
  • Investigate the Lorentz force law and its applications
  • Learn about the effects of current direction on magnetic interactions
USEFUL FOR

Students of physics, educators teaching electromagnetism, and anyone interested in understanding the principles of magnetic fields and forces in current-carrying conductors.

Homework Statement


What will happen to the two wires shown in the diagram (in the attachments)?

A: nothing will happen
B: repel each other
C: attract each other

The answer is "B", they will repel each other.

Homework Equations





The Attempt at a Solution


I thought it would attract because the current in the two wires are coming in from different directions/ sides signifying that the electric fields are not the same, and if the electric fields are different then there must be an attraction.

But that was just my guess, could someone tell me why the two wires repel each other instead of attract each other?

This is a question about magnetic fields, not electric fields.

Answer these:
(1) What is the magnetic field created by the bottom wire? (Use a right hand rule.)
(2) What force does that magnetic field exert on the top wire? (Use a right hand rule.)
