Question
The nature of magnetic field line passing through the center of current carrying circular loop is:
- Circular
- Ellipse
- Parabolic
- Straight line
Hint:
In a circular coil the field lines near the coil are circular but see the net effect of this lines and then answer the questions
The correct answer is: Straight line
- In a circular coil the field lines near the coil are circular because the field near edges is effected by only one small part of coil which is close to the point but as we move towards the center, the field is affected by all the parts of the coil equally and the sum of the effects is such that the field becomes nearly straight line
