Is cartridge Demagnetizing Necessary?

Benn awhile since I posted.  Hope you all are well during this crazy time.
Have a question.  Is cartridge demagnetizing necessary and/or does it actually yield sonic results.?  Also. I read that by playing a record and at the same time shorting the RCA tonearm cable plugs together will be just as effective as using an actual demagnetizer.  Is this true?
Thanks all for your responses.

I use the Sumiko Fluxbuster to demagnetise the electronics, the Cardas record to freshen up the system & cartrtidge.

But for most folk cleaning the stylus and records properly would be more beneficial in sound quality improvements.

What is going on? How does this work? 
The magnetic fields guide the electrons through the conductor in a more efficient manner than with standard electrical conduction, creating less distortion and interference. This new magnetic type of conduction yada yada blah blah blah

Good a story as any. 
Yes. High Fidelity Cables claim to drive the signal to the centre of the wire, which is the opposite of the old Lindsay Geyer magnetic cables where they drove the signal to the outside of the cable by using magnetic signal wire.

Neither cables sounded any good to my ears in my experience.
