Question
What is difference in the pattern of magnetic field due to a circular loop and inside a solenoid?
✓

Answer

Circular loop Solenoid
1. Circular loop has only one turn, so its induced north and south pole are just opposite and very close. In solenoid the induced south and north pole are some distance apart, as it has more number of turns.
2. Magnetic field is present inside circular loop. No magnetic field is inside because it gets cancelled by each circular loop.
