SUMMARY

The discussion focuses on calculating the magnitude and direction of the magnetic force acting on wire 1 due to the magnetic field produced by wire 2, utilizing the Lorentz Force principle. It emphasizes the importance of understanding the interaction between parallel wires carrying opposite currents, which results in a repulsive force. The conversation highlights the necessity of specifying the force per unit length when the length of the wires is not provided, as this is a common requirement in such problems.

PREREQUISITES
  • Understanding of the Lorentz Force
  • Knowledge of magnetic fields generated by current-carrying wires
  • Familiarity with the concept of force per unit length
  • Basic principles of electromagnetism
NEXT STEPS
  • Study the principles of the Lorentz Force in detail
  • Learn about the magnetic fields produced by parallel wires
  • Explore calculations involving force per unit length for current-carrying conductors
  • Review examples of magnetic force interactions between multiple wires
USEFUL FOR

Students of physics, electrical engineers, and anyone interested in mastering electromagnetism and the behavior of current-carrying wires in magnetic fields.

Could someone help me with this problem? I don't really know how to do it..

What is the magnitude and direction of force acting on wire 1 due to the magnetic field produced by wire 2?
 
Physics news on Phys.org
This type of problem is a huge deal, you should attempt to master it. It uses the Lorentz Force.

On that site too, here it has specifically the paraelle wires.

And since the currents are opposite, should repel from each other. Oh yeah, was there a length of one of the wires given too? I'll have to dig out my book, think it derived 2 infinite wires, I'll get back to you on that.
 
Unless the length of the wire is known, you'll have to specify the force per unit length.

Often, in problems like this, "force" is loosely asked for when really it should be "force per unit length". So, make sure you give the answer in the correct units.
