Spoiler summary: The loop inductance of a circular loop is about 25nH per inch of circumference. Remember: before you start using rules of thumb, be sure to read the Rule of Thumb #0: Use rules of ...

Learn how to calculate and understand the force on a wire loop entering a magnetic field in this detailed physics tutorial! We break down the concepts of magnetic flux, Lorentz force, and induced ...

If you are a radio amateur, you may be familiar with the magnetic loop antenna. It’s different from most conventional wire antennas, taking the form of a tuned circuit with a very large single-turn ...

Magnetic loop antennas are great if you are limited on space since they are just a potentially small loop of wire. The problem is, they are sharply tuned. You normally have an adjustment capacitor to ...
