Homework Statement
A 425 mA conventional current is induced in a 48.0cm wire moved through a magnetic field. A 11.5 Ω resistor is connected to the wire as shown in the diagram below. If the magnetic force acting on the wire is 323 mN, then determine the direction and magnitude of the velocity of the wire moving through the magnetic field.

Homework Equations
B=F/IL
EMF=BlvsinΘ
V=IR
The Attempt at a Solution
My first step was to solve for the magnetic flux using B=F/IL
B= 323x10^-3 / (0.425A)(0.48m)
B= 1.5833333T
For my second step I found the Voltage of the current and resistor using V=IR
V=(0.425A)(11.5Ω)
V=4.8875V
For my third step I used V=Blv to solve for velocity
4.8875/[(1.583333T)(0.48m)= v
6.430934591m/s = v
and then I plugged it into the formula EMF=Blvsinθ
EMF=(1.58333)(0.48)(6.430934591)(sin90°)
EMF= 4.8875V
I know this is mostly wrong but I didn't know any other way to attempt this.
Please help!
