Answer
(i)
(1) The pattern of magnetic field lines of a current carrying solenoid is shown below:
(2) The pattern of magnetic field lines of a bar magnet is shown below:
(ii) Distinguishing features between :
| Magnetic field lines of a current carrying solenoid | Magnetic field lines of a bar magnet |
|---|---|
| If we cut a solenoid into two halves, the magnetic field strength of the halves gets decreased. | When we cut a bar magnet into two halves, the magnetic properties do not change and both act as a magnet. |
| The poles of a solenoid can be altered and hence the direction of magnetic field lines. | In case of a bar magnet, it is fixed. |
