It would be in quadrant 1. So if I come across this problem on a test then I can assume that whichever B is larger then that's the direction the magnetic filed will take at a point?

direction of magentic field with two wires?? Homework Statement Two long, straight wires cross each other at right angles. Find the direction and magnitude of the magnetic field at point P, which is in the same plane as the two wires Homework Equations Bnet = B1 - B2 B= U0I/2pir...

ok so let me understand, for (a) B=-B1-B2 for (b) B=-B1+B2 for (c) B=B1-B2 is this how it would be?

maybe i need practice with the right hand rule lol when i apply the rhr for the first wire, my thumb points north and fingers clockwise when i apply the rhr for the second wire, my thumbs point south and the fingers counter clockwise. how exactly is direction changing with distance? this is...

so for the first part (a): B=B1-B2 B1= u5A / 2pi(.05) B2= (u5A / 2pi(.05) B= (u5A / 2pi(.05)) - (u5A / 2pi(.05)) the magnitude of the field in part a would be zero??

Homework Statement Two wires shown in figure p19.48 carry currents of 5.00A in opposite directions and are separated by 10cm. Find direction and magnitude of the net mag field. (a) at a point midway between the wires. (b) at point P1 (c) at point P2 Homework Equations B=B1+B2?? B= u0I /...
