Abstract
The present invention relates to a holding magnetizer, which can: maintain a strong magnetic force even if away from the tip of a driver bit, regardless of the length of the bit, when mounted on the bit so as to perform screw work; reduce or remove magnetic force when the magnetic force needs to be weakened in accordance with work circumstances; use a screw holding ability so as to prevent a screw from being separated from the bit and being lost; and remove iron powder, generated by screw abrasion during work, when the iron power is attached to the tip of the driver bit.
