What does the pattern of field lines inside the solenoid indicate ? How can this field be utilised to magnetise a piece of soft iron ? |
| Answer» SOLUTION :The PATTERN of field lines inside the solenoid indicates that the solenoid is now BEHAVING as a bar magnet with one end behaving as the NORTH pole and the other end as the south pole of the magnet If a piece of soft iron is placed inside the solenoid and a current is passed through the solenoid coil, the iron piece is magnetised and begins to behave as an ELECTROMAGNET. | |
