Studying Salt Damage to the World’s Crumbling Buildings
We sometimes hear of tourists getting into trouble for carving their initials into the walls of the Coliseum in Rome and other famous structures. However, the more serious damage to this architecture is caused by something else entirely — salt. Transported by wind and water droplets, and even found in some building materials, salt is a powerful mineral that can cause a building’s façade to crumble and break. Researchers studied this effect to better predict salt’s behavior and prevent damage.
Analyzing Mutual Inductance in Different Coil Arrangements
Mutual inductance measures the amount of change required for a current flowing through one circuit to create a current in a nearby circuit. Simulation can be used to compute mutual inductance.
