Ceramic magnetic plugs
Ceramic magnets have a large surface area
They are small but powerful for their size
Will retain magnetism through 350 degrees F.
Still retain 50 percent strength at 550 degrees
F.
A permanent magnet will also retain its
magnetism unless it is affected by a powerful electrical force.
Permanent magnets will lose magnetism about one
percent every ten years or so.
We use Grade 5 ceramic ferrite magnets
