Here you go

Thanks for all your help. The reason I started this thread is because we have to make presentations about physics in the industry and I chose my topic to be goal-line technology however seems like understanding and explaining technology isn't one of goalref and FIFA's top priorities so now I...

But how do we know if the ball has fully passed through and not just half of the ball? Does the disruption through the goal cage's magnetic field vary depending on how much of the ball goes through the magnetic field?

Another question: How does the wires placed around the goal produces magnetic field and if it did, how would the field look like?

Hi, I am interested in the basics of goalref technology however there is not many material out there. What i want to know is why does the magnetic fields have to be low frequency? and how does it detect if the ball has fully crossed the line? And lastly what is the purpose of the coils...
