I'm doing = a simple proximity alarm where I use a reed switch on a circuit board = with two pieces of steel on either side to stick to a neodymium = magnet.  The small circuit board will be sewn into one flap of a = pouch and the magnet to the flap. I'm using a PIC10F206 Microchip 6 pin = microcontroller to monitor the switch and chirp a small piezo = buzzer.  My question is will the magnet  have any affect on = the operation of the micro?  It is a small magnet just a bit bigger = than a penny.

Thanks

Should have no effect. Ordinary chips = are extremely insensitive to static magnetic fields.
