Study the Magnetic Field Pattern of Various Materials Using a Bar Magnet
1)What is the effect produced on a magnetic field when an electric current is passed through a wire?
  

2)What is magnetism?
  

3)How does the number of turns in a current-carrying coil affect the magnetic field produced?
  

4)What is induced magnetism?
  

5)What happens to the induced magnetism when the external magnetic field is removed?
  

6)Which of the following is an example of an induced magnet?
  

7)What is the magnetic field pattern around a bar magnet?
  

8)How can you induce magnetism in a non-magnetic material?
  

9)What is the SI unit of magnetic field strength?
  

10)How is induced magnetism different from the magnetism of a bar magnet?
