Copper Sheet Electromagnet

Next use wire strippers to remove some of the insulation from both ends of the wire.

Copper sheet electromagnet. To make an electromagnet wrap several inches of copper wire around an iron nail leaving 2 3 inches of wire loose on each end. I am s farmer so don t know a lot about this. His first electromagnet was a horseshoe shaped piece of iron that was wrapped with about 18 turns of bare copper wire insulated wire didn t exist yet the iron was varnished to insulate it from the windings. Danish scientist hans christian ørsted discovered in 1820 that electric currents create magnetic fields.

Exploration of a quixotic electromagnet for attracting aluminum copper and non ferrous metals like gold. But it works. British scientist william sturgeon invented the electromagnet in 1824. I used 26 gauge insulated copper wire.

If your high school science teacher ever told you. The copper itself is not magnetic but when its approached by magnets the electrons on the surface of the copper being rotating. Use insulation tape to secure the copper wire in place and it helps in unwinding of the coil. Hi i have just buyan electromagnet it s 75mm diameter 2 mm plate 14000 windings it s 5 mm thick i used 9 mm copper wire i did this so it was not an amp hog.

Use fire or sand paper to remove the insulation at the end terminals of the copper wire. It is not mandatory to wind the wires in order but make sure the layers are uniform. Mhe material handling electromagnets can be used to handle medium gauge sheet metal and plate. Wind around 900 1200 turns of copper wire.

Depending on the specifications of the magnet the sheet may be made of pure copper an excellent conductor or of a copper alloy copper beryllium copper zirconium or copper silver. Copper sheet metal scraps 1lb package of various size copper flat pieces 16 oz lead free copper 99 9 pure copper sheet metal 24 gauge copper 110 copper sheet unpolished mill finish astm b152 0 021 thickness 12 width 12 length. Then connect the stripped ends of the wire to a d battery by wrapping one around the positive end and the other around the negative end. Quality control dictates this process right from the get go.
