Everyone knows that used a compass can help you figure out what direction you should go.These can come in handy to help you navigate your way through a field or forest while camping. Magnetic compasses work based on Earth’s magnetic field. Today ,AIM Magnet show you how to make homemade magnetic compass with strong magnet.
First,we should prepare a sewing needle,a plastic bottle top about diameter 5-10mm,tack,sharp knife ,shallow dish of water, towel .The most important thing is that don’t forget the strong magnet.
Second ,magnetized sewing needle by rubbing strong magnet about 10 times from tail to tip. Always rub the strong magnet in same direction against sewing needle. Your needle should be magnetized.If strong magnet has marks north pole, then rub needle with this end.
Third,stick the magnetized needle to the plastic bottle top with some tack, to keep the needle floating on the water.
Fourth ,float the plastic bottle top in a dish of water. Water creates an almost friction less surface which allows the cork to rotate until the north pole of the needle points towards the magnetic north pole.
Fifth ,keep the dish of water and needle away from magnets and electronic, such as TV,screens ,cell phone and computers . Because they can disrupt the field lines.
Finally ,you can then check that the result by correct compass or a compass tool. The needle will slowly lose its magnetic charge over time.Is it so easy and interesting? If you want to know more magic thing about strong magnet. Welcome visited www.aimmagnet.com.
