Teaching HTET TGT Level 2 - 2024 Mock Test Physics Moving Charges and Magnetism Magnetic Field due to a Current Element
A circular loop of radius r is carrying current I A. The ratio of magnetic field at the center of circular loop and at a distance r from the center of the loop on its axis is:
1
\(2 \sqrt{2}:1\)
2
\(1:3 \sqrt{2}\)
3
\(1:\sqrt{2}\)
4
\(3 \sqrt{2}:2\)
