An electromagnet is powered by electrical current and that current can be adjusted to different levels of magnetism,Êso if you disable its electrical connection it will not work.
As inferred from the name, an electromagnet requires electricity in order to generate a magnetic field.
Yes it can because water will not interfere with the magnet as it is working
How does electromagnet work in separation? It is when calcinations is moved into a moving belt and passes under two pairs of electromagnets. The first pair of eleronmagnets is to draw off any iron ore the second pair attracts the wolframite.
An electromagnet works by focusing electricity into a metal bar with many windings of conductive wire and making it magnetic. Electricity passing through a wire makes a field. Concentrating that field makes an usable electromagnet. Faraday demonstrated this.
A cell or other (DC) power source must, indeed, be connected to an electromagnet to make it work. It is an electromagnet. Surf the link to our friends at Wikipedia. It's a good article, and the pics are cool.

the electromagnet makes the door close when a fire alarm goes off
Considering this work bench will be outside in the weather, make sure to get materials that withstand whatever your region throws at it. Some free plans with multible ideas are located at http://www.woodworkersworkshop.com/workbenches.php.
Metal
what do you need to work with
the armature
it connets to the bottom of the machine
A core
Yes but you would need a conducting pole of some kind to create the magnetic field.
stop trying to cheat on you home work
