Artificial Magnetic Fields — Electromagnetism (Physics Gr12)

AI Thread Summary
Two parallel conductors carrying 10 A of current in the same direction produce a magnetic field strength of 0 T at the midpoint between them. Conversely, if the currents run in opposite directions, the magnetic field strength at the same midpoint is 4.0 x 10^-4 T. Participants in the discussion suggest using the right-hand rule to visualize the magnetic fields. Drawing the wires "end on" and adding circular magnetic field lines helps clarify the interactions. The explanation and visual aids effectively resolve the confusion regarding magnetic field behavior in this scenario.

Homework Statement


Two parallel conductors each carry 10 A of current in the same direction.
a) What is the magnetic field strength at the midpoint between these wires? (answer = 0T)
b) What is the field strength at the same point if the current ran in opposite directions? (answer = 4.0x10^-4T)

I am very confused and any help would be greatly appreciated

Are you familiar with the right hand rule..

Make some drawings of the magnetic field with two wires.
 
Yes I am familiar with all three of them
 
Then I suggest drawing two wires "end on" and adding circular B field lines around each. See what happens in the middle.
 
Thanks, got it
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging 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...
