Solution

Dear Student
Biot Savrat Law affects the strength of magnetic field induced due to current flowing through the loop.

$B equals fraction numerator mu subscript o N I over denominator 2 R end fraction$

(1)When the loop’s radius is decreased as magnetic field strength formula is inversely proportional to radius of the loop, becomes double of the magnetic field strength.

(2) When the loop’s current is doubled as the magnetic field strength formula is directly proportional to current flowing in to the loop, becomes double of the magnetic field strength.
