Totally agree, there is a big difference to giving a calculator to someone who already knows how to do the math by hand, than giving it to someone who doesn't know how to do the math by hand in the first place.
It doesn't help you learn, and really can hinder the learing. If you only learn the trick and not the trade, you've learned nothing.
Being a motorcyclist I have also had trouble with induction rings.
The trick is to identify the ring, by the cut in the road.
Then to ride up one cut side of the ring as quickly as possible and stop abruptly at the end. If it's a double loop, the trick is to ride up the middle cut in the road.
And induction ring is creating a current like a motor does. But your bike, or my motorcycle is the magnet or metal in the motor, and the ring of wire is the coil. The speed and amount of metal makes a difference in the amount of current created.
Apparently once your stopped if you lean your bike over the ring, almost laying it down, it will help increase the current in the ring, changing the traffic signal.
The one day you'd sell your soul for something, souls are a glut.
