Question

Which of the following statement is correct regarding induced magnet?
1. It can not repel other magnets
2. they are permanent magnets
3. They don't have any magnetism.
4. All of the above statements are incorrect

Answer 1

Correct Answer - Option 1 : It can not repel other magnets

CONCEPT:

• Permanent magnets: A permanent magnet always causes a force on other magnets, or on magnetic materials.
  • They produce their own magnetic field.
  • Their magnetic field cannot be turned off. It is there all the time.
  • Example: Bar magnets, horseshoe magnets, etc.

• Induced magnets: An induced magnet only becomes a magnet when it is placed in a magnetic field.
  • When the magnet is removed from the magnetic field, The induced magnetism is quickly lost.
  • They are only attracted by other magnets,
  • They don't show repelling property like permanent magnets.

EXPLANATION:

• Option 1: Induced magnets can not repel other magnets
• Option 2: Induced magnets are not permanent magnets
• Option 3: Induced magnets do have any magnetism when placed in a magnetic field.
• So the correct statement is option 1.
