Magnetic Force on Current-Carrying Wire Video Lessons

Concept

# Problem: Calculate the uncertainty in the measured magnetic field in part A. The earth's magnetic field is approximately 10° -10° T. Explain why it is reasonable to ignore the effect of this field for this experiment. 1.Magnetic field: -0.92092 TLength of wire: 0.05 m

###### FREE Expert Solution

We are required to determine the uncertainty in a problem with a graph.

Magnetic force on a current-carrying conductor:

$\overline{){{\mathbf{F}}}_{{\mathbf{B}}}{\mathbf{=}}{\mathbit{N}}{\mathbf{B}}{\mathbf{i}}{\mathbf{Lsin\theta }}}$ N is the number of turns of wire in the magnetic field.
