Question

Formula magnetic field due to a current through a circular loop

Answer 1

Explanation:

→B=μ0→μ2πR3. If we consider y>>R in Equation, the expression reduces to an expression known as the magnetic field from a dipole: →B=μ0→μ2πy3. The calculation of the magnetic field due to the circular current loop at points off-axis requires rather complex mathematics, so we'll just look at the results.
