Question

11. A bar magnet is divided in two pieces. Which of the following statements is true?
(a) The bar magnet is demagnetized.
(b) The magnetic field of each separated piece becomes stronger.
(c) The magnetic poles are separated.
(d) Two new bar magnets are created​

Answer 1

Answer:

A bar magnet is divided in two pieces. So each half functins as a new separate bar magnet. (d)

Answer 2

When a bar magnet is divided into two pieces two new bar magnets are created. (Option d)

• A bar-shaped man-made magnet is called a bar magnet.
• They are made from ferromagnetic substances like steel, iron, etc.
• They are permanent magnets as a result, cutting them cannot demagnetize them.
• Poles of the bar magnet can never be separated. When it is cut into two, the two cut pieces will have their own north and south poles since magnetic poles exist in pairs.
• Dividing a bar magnet does not bring any change in its field strength.
