# Wire in an external magnetic field#

A long, straight, horizontal wire carries a left-to-right current of 24.5$$\rm\ A$$.The wire is placed in a uniform magnetic field of magnitude 29.0$$~\mu\mathrm{T}$$ that is directed vertically downward.

## Question Text#

What is the magnitude of the net magnetic field 16.5$$\rm\ cm$$ above the wire?

$$B=$$ $$\rm\ \mu T$$
