Abstract
The electromagnetic sweeper has many advantages over current magnetic sweepers. For example, one can turn off the electric current to release the ferrous material which has been captured by the sweeper. One does not have to pull off captured materials due to the use of electromagnets rather than permanent magnets. The device is also light weight and very easy to use.
Claims4
The device allows one to release captured ferrous materials with the push of a button.
The device allows one to collect ferrous materials by releasing them over a bucket.
The device does not require one to bend over to pull the collected material off of the magnets.
The device's push button operation means that one does not have to risk cutting one's fingers by manually removing captured ferrous material.
