How can we detect the poles of a solenoid?

The simplest way to find the poles of solenoid is by using a bar magnet. We can bring the North pole of a bar magnet closer to both the ends of the currnt carrying solenoid.

How will you find the polarity at the ends of solenoid without using magnetic needle?

Answer: It can be found out using the Right Hand Thumb Rule. The Direction of thumb represents the direction of current and the direction in which the remaining fingers are curled represents the direction of magnetic field helping us to find the magnetic polarities without using compass.

How can we determine the north and south pole of a solenoid?

Yes, the north and south poles of a current–carrying solenoid can be determined with the help of a bar magnet. If the magnet is repelled, the end is north end of the solenoid. If the magnet is attracted, the end is south end of the solenoid.

How do you determine the direction of a magnetic field in a solenoid?

Right-hand rule can be used to find the direction of the magnetic field. In this case, point the wrapped fingers (along the coil) in the direction of the conventional current. Then, the thumb will point to the direction of magnetic field within the solenoid.

Does a solenoid have poles?

A: Like a bar magnet, a solenoid has north and south magnetic poles and is surrounded by a magnetic field.

What will happen if a magnet is brought near a magnetic compass pointing the north south direction?

If a compass is brought near a magnet its needle gets deflected due to the magnetic field of magnet.

Why does a freely suspended magnet always comes to rest in the north south direction?

A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.

How can you determine the north pole of a current carrying solenoid with the help of a bar magnet?

Bring north pole of a bar magnet near one of its ends. In case the solenoid moves towards the bar magnet, that end of the solenoid is a south pole and in case the solenoid moves away from the magnet, that end of the solenoid is its north pole.

How does a solenoid behaves like a magnet?

The solenoid behaves like a magnet as it has a soft iron core with insulated copper wire over it. When a current is passed through the solenoid, a magnetic field is produced around it. The magnetic field produced is similar to the magnetic field of a bar magnet.

How does current pass through solenoid?

When electricity is passed through the solenoid, it acts as an electro magnet. The magnetic field produced by a current-carrying solenoid is similar to the magnetic field produced by a bar magnet. The magnetic field lines inside the solenoid are in the form of parallel straight lines.
