another EM

Magnetic resonance imaging needs a magnetic field strength of 1.5 T. The solenoid is 1.8 m long and 75 cm in diameter. It is tightly wound with a single layer of 2.50-mm-diameter superconducting wire.

What size current is needed?

Thanks in advance

    calculate the number of turns you can make, given diameter of wire, and length of the solenoid. Then use the solenoid equation to find current.

    i did. so length of solenoid is 1.8m. diameter of wire is 2.5e-3 m. so N=1.8/pi(2.5e-3)
    shouldnt that be right? with L being 1.8.

    got it thank you
