electromagnet to trip traffic lights?
10/23/11 at 21:10:18

I installed a 12 volt electromagnetic solenoid to my kickstand and ran it to a momentary switch on the handlebar. The idea was to energize the electromagnet in the solenoid pushing a pulse down into the road surface. Unfortunately, the power of the electromagnet was so weak that it will only pull a compass needle if the compass is actually touching the solenoid. Huh

Then I found a small 12 volt electromagnet that draws 4 amps and pulls 100 pounds. That ought to do the trick!
Now it dawns on me that this much magnetism just might have an impact on the ignition module. Any ideas or incites?

The solenoid will be so far away from the rectifier and ignition, it won't make any difference. There might be a concern about the voltage spike when you actuate it, but it doesn't seem to me it would be any worse than the spike of the starter or the decompression solenoid.

What I'm wondering is if these gizmos do any good at all to trigger traffic lights. All the lights around here (metro Atlanta) use a system that has a wire loop about 8' by 20' buried in the asphalt.

These guys seem to have a solution that works:

If you're on a motorcycle you can pull in the clutch, stop the engine, and press the engine starter button. The starter is powered by an electromagnetic motor, creating more magnetic energy and tripping the sensor."

Or, just avoid those intersections where there are known sensors.

Reply #7 - 10/24/11 at 12:25:18 Our state has a law that was passed allowing bikes to go through a red-light intersection if it doesn't change for one full cycle. Never had to test that yet myself.
