A degaussing unit was a 21st century piece of technology that presumably could be used to eliminate a magnetic field.


The October 22, 2015 issue of USA Today stated that Marty McFly, Jr. had been caught with a stolen degaussing unit after setting off an alarm in an attempt to break into the Hill Valley Payroll Substation on 8th Street.[1] After history was altered by the arrest of Griff's gang, both the break-in and Marty Jr.'s arrest never happened.
