Teaching RPSC School Lecturer Mock Test Series 2024 Physics Moving Charges and Magnetism Magnetic Field on the Axis of a Circular Current Loop
A very long wire ABDMNDC is shown in figure carrying current I. AB and BC parts are straight, long and at right angle. At D wire forms a circular turn DMND of radius R. AB, BC parts are tangential to circular turn at N and D. Magnetic field at the centre of circle is :
1
\(\frac{\mu_0 \text{I}}{2 \pi \text{R}}\left(\pi+\frac{1}{\sqrt{2}}\right)\)
2
\(\frac{\mu_0 \text{I}}{2 \pi \text{R}}\left(\pi−\frac{1}{\sqrt{2}}\right)\)
3
\(\frac{\mu_0 \text{I}}{2\text{R}}\)
4
\(\frac{\mu_0 \text{I}}{2 \pi \text{R}}(\pi+1)\)
