A 20 turn circular coil of length 5.9 cm produces a magnetic field of magnitude 1.9 mT at its center. Find the current in the loop

2. Relevant equations

B=(moconstant)nI

where n is the number of turns per unit length and I is current. magnetic field is B

3. The attempt at a solution

so i put in .0019 T for B

i put in .059 m and divided 20 by that to find the turns per unit or m

i plugged them in with the constant and got a red x... any suggestions?
