Homework Help Overview

The discussion revolves around the impossibility of a scenario involving two parallel copper conductors carrying currents in opposite directions. The problem specifies their lengths, radii, and the magnetic force they exert on each other.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the nature of the magnetic fields produced by the conductors and question whether these fields would cancel each other out. There is also confusion regarding the configuration of the conductors, whether they are straight or circular.

Discussion Status

Some participants have offered differing views on the behavior of the magnetic fields, indicating a lack of consensus on the fundamental principles at play. Clarifications about the setup and assumptions are being sought.

Contextual Notes

There appears to be uncertainty regarding the physical arrangement of the conductors and the implications of their current directions on the magnetic forces involved.

1. Why is the following situation impossible? Two parallel copper
conductors each have length , L = 0.500 m and radius
r = 250 mm. They carry currents I = 10.0 A in opposite
directions and repel each other with a magnetic force FB =
1.00 N.



Homework Equations





3. I am thinking that it would be impossible since the magnetic field would cancel. is this right?
 
Physics news on Phys.org
no they would not cancel
 
I think i need help understanding if this is two long parallel conductors or is it a circle?
 
opposite current carrying rods repel each other
