1. The problem statement, all variables and given/known data A stiff wire 42.0cm long is bent at a right angle in the middle. One section lies along the z axis and the other is along the line y=2x in the xy plane. A current of 15.0 A flows in the wire-down the z axis and out the line in the xy plane. The wire passes through a uniform magnetic field given by B = (0.318i) T. 2. Relevant equations F = I * l x B 3. The attempt at a solution I am given all the elements, Current, length of wire, and Magnetic Field. I know that I have to figure out the cross product of the length and the magnetic field vectors, but this is where I have the most trouble. If I am looking at my notebook I am using an xy plane where the y axis is up/down and x is horizontal, same as we all learned in calculus. The z axis is the depth. Since the current is flowing down the z axis it is flowing into the page, so to speak.My graph diagram might look like this for the xy axis ...........y ...........| / y = 2x _______|/___________ x ........../| ........./ | with the z axis as depth (in and out of the screen) The length of each half of the wire is 0.21m. To find the angle I use old trusty TOA (tanθ = o/a) to give me an angle of 63.4° To find my x and y magnitudes I use SOH and CAH x = cos(63.4°)*0.21m = 0.09m y = sin(63.4°)*0.21m = 0.19m and since Z is flowing into the page does that mean that my z vector is 0.21m? Any help at this point is appreciated. I am going to continue trying to work this out while I wait for help.
