Shielded vs. Unshielded Square Magnetic Field Loops for EMI/ESD Design and Troubleshooting

In this article, square unshielded wire loops are compared to shielded solutions including simple techniques to build them in your lab. Some examples are included to show that unshielded loops often work as well as shielded loops in some applications, especially for injecting signals into circuits.
