Question

why current loop behave like magnetic dipole moment

Answer 1

First , to understand how a magnetic dipole in a current loop works , you should understand how magnetic field is generated for a straight current carrying conductor .
What we are expecting to find here is where the two poles are for a magnetic field generated by a straight current carrying conductor . Here you will find a very counter intuitive truth , there is no north or south pole in magnetism , those are the terms which we use to represent the points where magnetic field diverges in all directions and point where it converges from all directions respectively
