here's ur answer!!!

you will need:-

1.A large iron nail (about 3 inches)
2.About 3 feet of THIN COATED copper wire
3.A fresh D size battery
4.Some paper clips or other small magnetic objects.


what to do:

1.. Leave about 8 inches of wire loose at one end and wrap most of the rest of the wire around the nail. Try not to overlap the wires.

2. Cut the wire (if needed) so that there is about another 8 inches loose at the other end too.

3. Now remove about an inch of the plastic coating from both ends of the wire and attach the one wire to one end of a battery and the other wire to the other end of the battery. See picture below. (It is best to tape the wires to the battery – be careful though, the wire could get very hot!)

4. Now you have an ELECTROMAGNET! Put the point of the nail near a few paper clips and it should pick them up!
NOTE: Making an electromagnet uses up the battery somewhat quickly which is why the battery may get warm, so disconnect the wires when you are done exploring.

hope this helps...

Hello there!!
I'm Rajdeep....

An electromagnet is a device which has many advantages over permanent magnet!
You can switch it on and off any times....To make it, follow the following steps:

1. A solenoid can be made, which functions as a electromagnet.

2. Take a soft iron rod...don't use steel, because retentivity of steel is very high and even after switching off the current through the coil, it will retain its magnetic power. So use a soft iron rod.

3. Take an insulated copper wire and wound it around the soft iron rod.

4. Connect a switch to the live wire and a dc source of energy, for example, a 9V battery.

5. Your electromagnet is ready! Switch on the current and see its power. Remember, more the number if turns, more is the strength of the magnet!!

Thanks...
Hope you liked it....
