If you push a coil of wire through a magnetic field where the field direction is perpendicular to the plane of the coil and the direction of the coils velocity, a voltage is induced in the coil with a magnitude
V=NBlv
where N is the number of turns in the coil, B is the magnitude of the magnetic field, l is the length of the side of the coil that is perpendicular to the velocity direction and lowercase v is the velocity of the coil. If you make a plot of Voltage vs velocity, the slope of that graph will be NBl. Add calculations to the cell block below to find the predicted value of the slope, along with its uncertainty. You may use either the functional or calculus method to find the uncertainty. Make sure that your answer has units and the appropriate number of digits.
I'm looking for the equation for the functional or calculus method to find the uncertainty.
