Magnetic Testing
Magnetic Testing is a way to check if metal parts in machines or structures have any hidden problems like cracks or weak spots. It works by using magnetic fields to find issues that can't be seen with just the eyes. This is important because it helps prevent equipment breakdowns by catching problems early. It's like giving machines a health check-up without having to take them apart. This method is also called Magnetic Particle Testing or MT, and it's one of several ways to check equipment safety without damaging the parts being tested.
