Magnetism and force on a conductor

Click For Summary
SUMMARY

The discussion centers on calculating the force on a conductor using the formula F = BIL, where B represents magnetic flux density, I is the current, and L is the length of the conductor. The user correctly calculated the force magnitude as 0.75 N by substituting B=0.25, I=15, and L=0.20 into the equation. However, there was a misunderstanding regarding the application of the right-hand rule; the correct method involves using Fleming's Left Hand Rule to determine the direction of the force.

PREREQUISITES
  • Understanding of magnetic flux density (B)
  • Knowledge of current (I) in electrical circuits
  • Familiarity with the concept of length (L) in physics
  • Proficiency in applying Fleming's Left Hand Rule
NEXT STEPS
  • Study the application of Fleming's Left Hand Rule in electromagnetic contexts
  • Explore variations of the force equation F = BIL with different configurations
  • Learn about the implications of magnetic fields on current-carrying conductors
  • Investigate real-world applications of magnetic force in electrical engineering
USEFUL FOR

Students studying electromagnetism, physics educators, and anyone involved in electrical engineering or related fields seeking to understand the interaction between magnetic fields and electric currents.

Homework Statement


The question is as shown on the attachment.


Homework Equations


F = BIL


The Attempt at a Solution


To find the magnitude of the force I used the equation "F = BIL" and then I put in the values for each (B=0.25, I=15, L=0.20) and I got an answer (magnitude) of 0.75. Then using the right hand rule I found the direction of the force to be pointing to the right.

I just want to make sure, I am doing this right? Because the next three questions on my worksheet are very similar to this one except I am finding different things and I am given different values.

OK.
Then using the right hand rule I found the direction of the force to be pointing to the right.
How did you apply the right hand rule?
 


The way you found out the magnitude of the Magnetic Induction on the straight current carrying current is proper. Now, in order to find its direction, you need to apply Fleming's Left Hand Rule.
