Question

A student requires two magnets for a science project. He could find only one magnet and thus he decided to make another magnet from it. Which of these processes could be followed to create an additional magnet? *

a.Placing a piece of cardboard above the magnet
b.Placing the nail close to a magnet without touching it
c.Take a piece of iron nail and rub it repeatedly with the magnet
d.Wrapping a piece of plastic around the magnet for a few hours

Answer 1

placing the nailclose to a magnet without touching it may be

pls follow me

Answer 2

The right response to the given question is by the process described in option c: Take a piece of iron nail and rub it repeatedly with the magnet.

• Ferromagnetic substances are those which can become be easily magnetized when kept under the influence of a strong magnetic field.
• A piece of iron nail is made of iron elements and it can be easily magnetized by strong and permanent magnets.
• When a nail of iron is rubbed in a uniform direction in a repeated manner with the same speed it becomes magnetized.
• It can be rubbed over either of the poles of the magnet a number of times or even the magnet can be rubbed on the iron nail. It is called the single touch method of single touch for incorporating magnetic characteristics.
• The atoms of the particles present inside iron nails get arranged according to the field of true magnets employed here and start exhibiting magnetism or magnetic property.
• However, this magnet formed by the iron nail is an example of temporary magnetism, but it can attract things.
• Hence, the additional magnets can be created by students using nails of iron in the way described here.
