(adsbygoogle = window.adsbygoogle || []).push({}); 1. 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 2.20-mm-diameter superconducting wire.

2. B = mu_{0}BI / l

3. Is there a way to do this without finding N? Either way, how do I calculate N with the given information?
