I used the numbers I provided so:
I=12.0 A
B= 1.3 T
e= 1.6*10^(-19) C
V= 3.2*10^(-6) V
d= 0.8 mm (I left it because those are the units that the answer is in- but I'm guessing now that that is probably wrong).
What did I miss that is wrong in the calculation?
The Hall voltage across a 0.800-mm-thick conductor in a 1.30 T magnetic field is 3.2 uV when the current is 12.0 A.
What is the charge carrier denisty in the conductor (in m-3).
I was using the equation Vh=IB/ned
where Vh is the Hall voltage
I is the current
B is the magnetic field...
