Finding the Magnitude and Direction of Magnetic Field of 2 parallel wi

AI Thread Summary
The discussion focuses on calculating the magnetic field generated by two parallel wires carrying different currents. The first task is to determine the magnetic field's magnitude and direction at a midpoint between the wires, while the second task involves finding the magnetic field at a point above the wire with a higher current. Users are encouraged to provide a visual representation of the setup for better assistance. Additionally, detailed calculations using the relevant formula are requested to verify the user's attempts. Clear guidance is sought to resolve the calculation issues encountered.

Homework Statement


Two long, parallel wires carry currents of I1 = 2.78 A and I2 = 4.80 A in the direction indicated in the figure below. (Choose the line running from wire 1 to wire 2 as the positive x-direction and the line running upward as the positive y-direction.)

a) Find the magnitude and direction of the magnetic field at a point midway between the wires (d = 20.0 cm).

(b) Find the magnitude and direction of the magnetic field at point P, located d = 20.0 cm above the wire carrying the 4.80-A current.

Homework Equations



F=BILsin(theta) not sure if that is the one to even use

The Attempt at a Solution


tried plugging in the numbers in the above equation, but not working. Help is greatly appreciated!

Welcome to the PF.

Can you scan or take a picture of the figure and upload it as an attachment? That would help us help you with this.

And when you upload it, please show your detailed calculations using that formula, so we can check your work.
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
