CMS Magnetics - Magnetic Pole Detector, a Handy Polarity Identifier to Determine Magnet's North or South Poles, Great for School Teachers, Science Projects, and Metal Detector

CMS Magnetics - Magnetic Pole Detector, a Handy Polarity Identifier to Determine Magnet's North or South Poles, Great for School Teachers, Science Projects, and Metal Detector

Q: Is red north on this magnet? So when you test a magnet and the red side points towards it, that would be the south side of the magnet?

Ignore some of the reviews where people give incorrect information and say this magnet is colored wrong. It's not colored wrong. If checking guitar humbuckers for example, red points at the south coil; blue points at the north coil. Opposites attract. If you point this unit towards the earth's north pole, the red end will point to the north, because the north pole is negative charged; If you point this unit towards the south pole, the blue end will point to the south, as the south pole is positively charged.

Q: Can this be used to locate underground electrical wires?

A pole detector shows the direction of a magnetic field, and would respond to slow changes in the field strength and direction. Your underground wire would have to be carrying a direct current so as to generate a magnetic field with a constant field strength at any particular location. The pole detector has too high an inertia to respond to a magnetic field created by an alternating current at 60 Hz, for example. You need a metal detector if you are looking for underground wires. Whether the wire(s) were carrying any current or none would be immaterial to a typical metal detector.

Q: Would this be good to help with knowing where the new north and south poles would be after the upcoming Geo magnetic pole shift?

No. Read the item's description! The CMS Magnetics pole detector is for distinguishing a magnet's north and south poles, not the location of the earth's magnetic poles.

Q: Will this device reliably tell me the field orientation of brushless motor magnets?

I don't know what your motor magnets consist of, but this simple, reliable device will indicate north and south poles on any permanent magnet. If you are looking for a stable electromagnetic field, this will also suffice. If you are looking for something while a motor is in motion, or for a changing magnetic field, then this may not be your answer and you are on your own.
