Questions
A short bar magnet produces magnetic fields of equal induction at two points; one on the axial line and the other on the equatorial line. What is the ratio of their distances?
detailed solution
Correct option is B
Given Baxial=Bequatorial ⇒μ04π2Md 13=μ04πMd23 ⇒d1d23=21 ⇒d1d2=2131Talk to our academic expert!
