Video advice: How to Magnetize a Nail (ON15 P35 Q2)ĩ702/35/O/N/15: Technique to magnetize objects. If you are doing a display project, that is all you need to do as your experiment otherwise you need to compare the strength of magnets made in different methods. In this experiment you will magnetize a few identical nails with different methods as described in the gathering information section. If held in contact with one end of a nail, the nail will begin to exhibit magnetism and will be able to pick up small iron objects such as paper clips and iron filings. Often made of hard steel, permanent magnets retain their magnetism once they’ve been magnetized. You can purchase permanent magnets in hardware and hobby supply stores and even in junkyards. Prolonged Contact With a Magnet The fastest way to magnetize a nail involves creating prolonged contact with a permanent magnet of sufficient strength. TL DR (Too Long Didn’t Read) You can magnetize a nail by touching a magnet to it, by prolonged contact with a magnet, or by building an electromagnet from it. Simple experiments such as these can teach basic principles of magnetism in science class and generate discussions about natural phenomena such as the earth’s magnetic field. He can turn a nail into an electromagnet, or permanently magnetize it by rubbing it with another magnet. Prolonged Contact With a Magnet – With only basic materials such as a permanent magnet, electrical wires and a battery, a teacher can demonstrate different ways to magnetize an iron nail. You can magnetize a nail by rubbing a magnet on it, with prolonged contact with a magnet, or by making an electromagnet out of it. Electromagnets can become permanent magnets if certain materials like steel and special alloys are placed in a coil and very strong current is passed through the coll. It is a temporary magnet and stops behaving like a magnet when the current is stopped. Electric current - A magnet made by using electric current is called an electromagnet. (A permanent magnet is brought close to the magnetic substance but not touched. The magnetic properties disappear when the influence of the magnetizing force is removed. Magnetizing by Induction - It is a method to make temporary magnets under the influence of a magnetizing force. Double-touch method - Opposite poles of two magnets are placed next to each other at the center of the magnetic substance and rubbed in opposite direction along it.
Single-touch method - A magnet is rubbed along the magnetic substance from one end to another. Was this answer helpful? – Open in AppMethods of magnetizing a magnetic material are :1.
