Question

A current carrying solenoid coil is suspended freely.in which direction will it settle
and why?​

Answer 1

Answer:

A solenoid behaves like a bar magnet. When it is suspended freely, it interacts with the Earth's magnetic field and aligns itself along the north-south direction.

Answer 2

Answer:

To know the reason behind this, we must first discuss what exactly is a solenoid.

A solenoid is a type of electromagnet made of soft iron core. Which gains the properties of magnets when current passes through the soft iron core .

Now there is a property of magnets which is called Directive property of magnet. This property of magnet says that a freely suspended bar magnet always comes to rest and align itself with earths magnetic field and comes to rest in North - South direction.

Now it is given that the solenoid is carrying current, now this solenoid will aquire properties of magnet because current is passing through it.

Now it will also aquire Directive property of magnets. Therefore at the end it will settle in North - South direction.
