Question
Transcribed Image Text:Figure (a) shows a length of wire carrying a
current i and bent into a circular coil of one
turn. In Figure (b) the same length of wire
has been bent to give a coil of 5 turns, each
of 1/5 the original radius. (a) If Bå and B₂
are the magnitudes of the magnetic fields
at the centers of the two coils, what is the
ratio Bb/Ba? (b) What is the ratio µ/μg, of
the dipole moment magnitudes of the
coils?
