Why solenoid is considered as bar magnet ?
Answers
Answer:
In order to understand how a bar magnet is equivalent to a solenoid, it becomes important to understand what is a bar magnet and what is a solenoid and what are their similarities and differences.
What is a Bar Magnet?
A bar magnet is a rectangular or a square piece of an object made from iron or steel having permanent magnetic properties with two poles: north and south.
What is a Solenoid?
A solenoid is a coil with the length greater than its diameter and is a type of an electromagnet to produce controlled magnetic fields by passing an electric current through it.
Answer:
Magnetic field lines are produced around the solenoid when a current is allowed to flow through it. The magnetic field produced by it is similar to the magnetic field of a bar magnet. ... Hence, one end of the solenoid behaves as a north pole and the other end behaves as a south pole.
