Introduction: Strong Electromagnet
How to make a very Simple Magnet with strong magnetic field
Step 1: Prepair a Nail or Any Iron Object
Using any metal which can be sucked by a magnet ( iron is the best). Don't use copper because it can't be sucked by a magnet
Step 2: Prepair Copper Wire With Insulation
You can get these in motor, transformer or buy them with very cheap price in the hardware store. Thicker wire - more magnetic field
Step 3: Wrap the Wire Around the Metal Object
More turn - More magnetic field generated
Step 4: Remove Insulation
Using sandpaper to remove the insulation in two ending of the coil
Step 5: Test the Magnet
Only 5 volt from USB can make very strong effect
