A long solenoid of length $L$ and radius $r$ carries a current $I$. A small loop of wire of radius $a$ is placed at a dis ance $x$ from the center of the solenoid. If the magnetic field at the center of the solenoid is $B_0$, what is the magnetic field at the center of the small loop?

Question

A long solenoid of length $L$ and radius $r$ carries a current $I$. A small loop of wire of radius $a$ is placed at a dis	ance $x$ from the center of the solenoid. If the magnetic field at the center of the solenoid is $B_0$, what is the magnetic field at the center of the small loop?

Accepted Answer

$ B_0 \left\( 1 - \frac{x}{\sqrt{x^2 + a^2}} \right $
