An airport worker uses an electromagnetic sweeper as he drives down the taxiway for an airplane. What adjustment can the worker make to cause the magnetic sweeper to be stronger when picking up debris (junk) on the runway? (1 point)
The airport worker can adjust the height or distance of the electromagnetic sweeper from the ground. By lowering the sweeper closer to the ground, the magnetic field created by the sweeper will have a stronger attraction to the debris on the runway, increasing its effectiveness in picking it up.
