A large iron nail. Rub the rod with two magnets drawing the north pole of one magnet from the center of the rod to one end while you draw the south pole of the other magnet in the opposite direction.

How To Make A Magnet With Pictures Wikihow

The domains align with the field and retain a good deal of that alignment when the field is removed resulting in a magnet.

How to make iron magnetic. Ferromagnetism along with the similar effect ferrimagnetism is the strongest type and is responsible for the common phenomenon of magnetism in magnets encountered in everyday life. This allows the field to be turned on and off. Electromagnets are created by running an electric current through a piece of metal to create a magnetic field.

A good way to do this is to attach a magnet to the outside of the dish. 3 feet of thin coated copper wire. Small magnetic objects like paperclips or pins.

Among the methods henry mentions for turning an ordinary iron or steel rod into a magnet are. Rub the rod with a piece of metal that is already magnetized. Then stroke the north end of the magnet against the metal about a dozen times in the same direction to create a magnetic charge.

To make a permanent magnet a piece of hard iron is placed in a magnetic field. Try to pick up some nails to see if it worked. This is your ferrofluid.

This can be done on a small scale using these supplies which are available at hardware stores. Use a napkin to absorb any excess oil and allow the ferrofluid to become thicker. Ferromagnetism is the basic mechanism by which certain materials such as iron form permanent magnets or are attracted to magnets in physics several different types of magnetism are distinguished.

Pour iron filings into the oil and mix the two until they have become a thick sludge like material. If not repeat the process or try magnetizing a different metal with a higher iron content. The iron will fall toward the magnet at the bottom.

To make an iron bar into a magnet you need to get a bar magnet and stroke the iron one way when you get to the end of iron take the magnet off and jump it back to the start and stroke repeat this. Another less messy option is to swirl the powder with the magnet under the container. If you heat the mixture over a bunsen burner hot plate or stove the mixture will start to glow.
