The magnet can cause the alignment of electron domains in the metal screw driver on rubbing, causing magnetism.
The magnetism in a permanent magnet is produced by magnetic moments of electrons in the magnet's constituent material. The material's atoms are each like tiny magnet bars. As a result of the quantum mechanical effect, the majority of these tiny magnets now prefer to align in a single direction to form domains, consequently magnetizing the entire substance.
Electrons exist in magnetic metals as well, although they are arranged differently. A strong magnet has a magnetic field strong enough to cause residual magnetism in the metal screwdriver by aligning the domains in it on rubbing with the metal.

Work = Fdcos(alpha)
Where F is force, D is distance, and Alpha is the angle to the parallel plane (in this case the ground)
I’ll assume alpha is 0 since it’s not given
100 • 12 • cos(0) = 1200 ft-lbs
