1. The problem statement, all variables and given/known data A 0.20 m long solenoid contains 1000 turns and carries a current of 5.0 A. What is the strength of the magnetic field at the center of the solenoid if its radius is 10-2m? a. 35.1*10-1T b. 8.2*10-1T c. .95*10-2T *d. 6.3*10-3T 2. Relevant equations B=μo*nI/l 3. The attempt at a solution B=(4∏*10^-7)*1000*5A/.2m B=3.14x10^-2T the answer key says its 6.3x10^-3T...what am I doing wrong?
