# Magnetic Field Strength

Not what you're looking for?

A piece of copper wire has a resistance per unit length of 6.45E-3 omega/m. The wire is wound into a thin, flat coil of many turns that has a radius of 0.170 m. The ends of the wire are connected to a 12.0 V battery. Find the magnetic field strength at the center of the coil. Answer in T.

##### Solution Summary

The answer is given step-by-step equationally.

##### Solution Preview

Because,
B = 10^(-7)*pi*N*I/r
r = radius = 0.170 m
I = V/R
<V = 12 Volt
R = resistance = 6.45*10^(-3)*l
where l is the length ...
