Yep, all you got to do is get some copper wire and a 9 volt battery, and wrap the wire repeatedly around the metal part of the screwdriver, and connect the wire one end to the positive terminal of the battery, the other to the negative end, then let it sit for an hour or two and the screwdriver will now be able to better grip screws and such.
You should use a ferromagnetic material, such as iron or steel, to make an electromagnet. These materials have strong magnetic properties that are necessary for creating a powerful electromagnet.
To make an electromagnet stronger, you can increase the current flowing through the coil, increase the number of turns in the coil, or use a material with high magnetic permeability as the core of the electromagnet, such as iron.
NO, even on a flat screwdriver the end is not sharp enough to chisel. If you make it sharp, then it loses it's value as a screwdriver.
Increase the number of coils in the electromagnet. Use a stronger magnetic material in the core of the electromagnet. Increase the current flowing through the wire winding of the electromagnet.
He wound wire around it to make a tranformer.

Increase the number of coils in the wire, increase the current flowing through the wire, and use a stronger magnetic material for the core of the electromagnet.
To make an electromagnet weaker, you can decrease the number of turns in the coil, reduce the current flowing through the coil, or use a material with lower magnetic permeability for the core. These methods will reduce the magnetic field strength generated by the electromagnet.
