Object: How big is a 400 gauss magnet?
I plan on using a magnetic sensor, perhaps the one listed below. It
states that it activates with a magnetic force from 195 gauss to 300
gauss. What size magnet would this be, and from what range would it
work? I'm hoping for a range of about 2 inches or so with a magnet
around 1 inch in diameter? Is this possible?
