Will a dynamo in the front bicycle wheel hub interfere with wireless bike computer?

I bought a new commuter bike, comes with dynamo-powered lights in front and rear, dynamo located in front hub, a wire running up inside the right hand fork. I have suspicions that this will cause interference with a wireless bike computer's sensor as the hub will contain strong magnets and the electric current running in the wire within the fork will also generate a magnetic field, all in the close proximity of the sensor. Just curious if anyone has had an experience with respect to this? I will likely return the bike computer anyway because of the ridiculous (for my bike) distance needed between sensor and magnet (5 mm).
 
It has been noted that hub dynamo lighting systems can interfere with wireless computer systems. I use wired computers with my hub dynamo systems. Even the ones with rear hub dyno systems.

Why is 5mm a ridiculous distance? Is this space too large or too small? There are solutions to both of these problems.
