A solenoid 77.1 cm long has 340 turns and a radius of 1.92 cm. If it carries a current of 1.85 A, find the magnetic field along the axis at its center. Answer in units of T.(adsbygoogle = window.adsbygoogle || []).push({});

I know the formula for the magnetic field is:

Magnetic field = permeability x turn density x current

I entered -

B=(1.25664x10^-6)(340/.771)(1.85)
