    Biot-savart Db
AI Thread Summary
The discussion revolves around a Biot-Savart problem involving a current element represented as Idx(ax+ay) A at point P(1,-2,2) and the need to find the magnetic flux density at point P(2,-1,3). Participants express confusion about the meaning of Idx and whether it should be treated as Idl for calculating the cross product with the vector r. There is uncertainty regarding the type of current element involved, with suggestions that it could be an infinite wire or a point source. The necessity of integration to determine the magnetic field B is also questioned. Clarification on these points is essential for solving the problem effectively.

i personally think that this is just a very simple problem since the problem only requires plugging the right values into the formula. I'm just having trouble with one minor detail.

Homework Statement



For the current element Idx(ax+ay) A situated at P(1,-2,2), find the magnetic flux densities at P(2,-1,3).

Homework Equations



Biot-Savart

dB = (K)(IdI x r)/rr

The Attempt at a Solution



my only problem in here is that I'm having a hard time figuring out what idx is? do i just substitute it for Idl then just get its cross product with r and so on? also, do i need to actually integrate it to get B?

that is all and thanks.

What is Idx(ax+ay) ?
What kind of current element do we have here ? Wire, infinite wire, semi infinite wire ?

hmmm...never thought of that question, marlon...

i suppose that it is an infinite wire? or can't it just be just a point with such property? will it actually make a difference?

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
