demagnetise
Strip magnetic charge
To demagnetise is to remove or reduce the magnetic properties of something.
Metal tools that have become magnetised can be demagnetised to prevent them attracting unwanted particles.
The spelling with -ise is British; American English uses demagnetize.
The technician demagnetised the old hard drive before disposal.
