A coil with a length equal to 10 cm is in air. Coil diameter issmall relative to the length of the coil. Running through thewindings of the coil a current I. The figure below gives themagnitude |B~| of the magnetic field B~ in the center of the coilas a function of the current. The permeability of air is equated tothat of vacuum. (T) 0 1 2 3 4 I (A) 0 8p.10-3 16p.10-3 B The numberof turns of this coil is:
<A> 314. <B> 628. <C> 1000. <D>10000.
c is the correct answer.
please explain this to me in detail, step by step.
