This is a real life electromagnetic crane . This is our electromagnetic crane in progress .

The re-design process has been used quite often , we had  to make 3 models before we finally got it right .

-washers -eye lit screws -2 batteries -wooden base -square dowels -paper clip -electromagnetic wires -screws -nail -paint sticks -wooden battery holder -bolt w/ electromagnetic electromagnetic wire -zip ties -cup holder screw

one place to another . This diagram is to show exactly  how this works and what it does . Our crane does this same thing, but instead of large metals , we move small things such as screws . The electromagnet on the crane picks the metals up using magnetism . It then brings it over and cutting/clicking off the magnetism, it releases the metal from the magnets "grip". Tools

Used

:

-band saw  -drill press -handheld drill -handheld impact driver -clamp - wire cutter -pliers

H bridge  An H bridge is an electronic circuit that enables a voltage to be applied across a load in either direction. These circuits are often used in robotics and other  applications to allow DC motors to run forwards and backwards.

fer·rous adjective

(chiefly of metals) containing or consisting of  iron.
