A screwdriver can become magnetic when it is made from a ferrous material like steel. When exposed to a magnetic field or magnet, the steel in the screwdriver can become magnetized, allowing it to attract and hold onto metal screws or other magnetic objects.

The mechanical advantage of a screwdriver is determined by the ratio of the length of the handle to the length of the shaft. For the 5 cm handle and 1 cm shaft, the mechanical advantage is 5:1, while the 3 cm handle with a 1 cm shaft has a mechanical advantage of 3:1. Therefore, the screwdriver with the 5 cm handle provides a greater mechanical advantage.
The best screwdriver for electrical work is a insulated screwdriver with a rubberized handle to prevent electric shock.
the effort is where u put work into the screwdriver- the handle.
Every screwdriver has a handle. You hold the handle and turn it to tighten or loosen a screw. Sometimes your screw might be in a tight place that your hand can't get to such as inside of a car hood. You use a long reach screwdriver because the shaft above the handle is larger than a typical screwdriver. A typical screwdriver shaft is about 5 inches. A long reach screwdriver is bigger. Maybe 12 inches or 2 feet long. It's just a long screwdriver. I can't believe you would as this question
It's cheaper and lighter than a metal handle would be.
A phillips screwdriver is generally made of a steel shaft with a plastic handle
There are a few ways . . . 1. Point the screwdriver north and south, then tap on it for a while with a hammer or other steel device. 2. Rub the screwdriver for its entire length with a magnet for a while.
Rub it against a magnet repeatedly. * The screwdriver can only be magnetized if made from steel or another magnetic metal, and most of them are. * Once magnetized, the screwdriver will remain magnetized always.
