Explain with a reason whether the field will be stronger at the centre of current carrying loop or near the circumference of the loop.
Answers
We know, when magnetic field is directly proportional to magnetic lines of force . Means if magnetic lines of force are more concentrated at a point respect to another point then that point have more magnetic field with respect to the point which contains less concentrated magnetic lines of force.
In case of circular loop, magnetic lines of force are highly concentrated at centre as shown in figure. so, magnetic field is strong at centre . While in case of circumference , magnetic field is weaker than centre
