There is one large magnet on the bottom of a push magnetic sweeper. The magnet is not along the entire width of the push magnetic sweeper as it is generally placed in a central position in its casing. Therefore, the magnetic width and the width of the magnetic sweeper is always different.
Push magnetic sweeper wheels
The wheels on a push magnetic sweeper are solid rubber which makes them puncture proof. Each push type magnetic sweeper has two wheels.
Push magnetic sweeper handle
The handle is used to push the magnetic sweeper around.
Push magnetic sweeper casing
The casing is made of either aluminium or stainless steel. These metals are both corrosion resistant which is beneficial to a magnetic sweeper due to its extended use outside.
The casing has two roles, the first being to hold the magnet in position, and the second to make only the bottom section of the magnetic sweeper magnetic. The casing does this by using non-magnetic materials which stop the magnetic field of the magnet permeating the sides and top of the sweeper. This enables the magnetic sweeper to be used more accurately as the magnetic force is focused downwards to pick up material from the floor.
Push magnetic sweeper release system
There are two types of release system: the collar and the handle. Both types of release system work by causing the direction of the magnetic circuit to change. By using the release systems, the magnets are physically moved away from the collection surface which creates an air gap. The air gap changes the course of the magnetic circuit which affects the magnet’s pulling power, therefore the magnet will no longer pick up the material, effectively turning it off.
