Vector Potential Between Parallel Wires: Calculating & Differences

AI Thread Summary
Calculating the vector potential between two parallel wires carrying currents in opposite directions involves considering the contributions from both wires. The vector potential at a point is determined by the superposition of the potentials from each wire, taking into account their respective directions of current flow. The Biot-Savart law is essential for these calculations, though it can be complex. The key difference in this scenario compared to a single wire is the interaction between the opposing currents, which affects the overall vector potential. Understanding these principles is crucial for accurate calculations in electromagnetism.

Hi All,

I've just looked at an example for calculating the vector potential for a point in the vicinity of a long straight wire.

I've now got to calculate the vector potential for a point between 2 parallel straight wires carrying currents in opposite directions. How does the vector potential differ in this case.

By the way...study biot-savart is giving me a headache :)

I would think you just add them together (with the appropriate sign).
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
