What is meant by solenoid? How does a current carrying solenoid behave? Give
its main use.
Answers
Explanation:
A closely bound cylindrical coil of insulated metallic wire. A current carrying solenoid behaves as an electromagnet. ... The field lines around a current-carrying solenoid is similar to that produced by a bar magnet. This means that a current - carrying solenoid behaves as having a north pole and the South Pole.
A closely bound cylindrical coil of insulated metallic wire. A current carrying solenoid behaves as an electromagnet. The uniform, magnetic field inside it may magnetise a steel rod permanently. Detailed Answer: A coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder is called a Solenoid. The field lines around a current-carrying solenoid is similar to that produced by a bar magnet. This means that a current - carrying solenoid behaves as having a north pole and the South Pole. The strong magnetic field produced inside a solenoid can be used to magnetise a piece of magnetic material like soft iron when placed inside the coil.
uses:
Solenoid: A coil of many circular turns of insulated copper wire wound on a cylindrical insulating body (i.e., cardboard etc.) such that its length is greater than its diameter is called solenoid. When current is flowing through the solenoid, the magnetic field line pattern resembles exactly with those of a bar magnet with the fixed polarity, i.e. North and South pole at its ends and it acquires the directive and attractive properties similar to bar magnet. Hence, the current carrying solenoid behave as a bar magnet. Use of current carrying Solenoid: It is used to form a temporary magnet called electromagnet as well as permanent magnet.
