Show I Demagnetizing a Watch A novel method of removing magnetism I from watches is due to Mr P D Richards of West Medford Mass The apparatus I consists of a compound horseshoe magnet placed erect with its poles upward and a I suitable support placed at some distance perhaps two or three feet above it From this support is suspended by a twisted 1 thread a cardboard tray in which is the I watch to be demagnetized Wheu in position posi-tion the supporting thread is allowed to I untwist and the watch is gradually removed re-moved from the magnetic field Of course the same results could be obtained by the use of an electro magnet energized from a battery or other source of current as well as by employing permapent horseshoe magnets mag-nets Electrical Work |
