What is solenoid what is the direction of lines of force around it?
Turning the solenoid around means that all field lines either point outwards or they all point inwards. Moving the solenoid along the axis means this happens for every little bit of the solenoid. But if all the field lines point outwards everywhere, then field lines have to start in the middle of the solenoid.
What will happen when the direction of current in the solenoid is reversed explain?
The direction of magnetic field is always perpendicular to the direction of current flow and the magnitude of the magnetic field inside a solenoid is directly proportional to the current flowing through the solenoid. Thus,when the current through the solenoid is reversed,the direction of magnetic field is reversed.
What will happen when the direction of current flowing through the rod is reversed?
Hence if we reverse the current the direction of magnetism also reverses. In other words the magnetic poles gets reversed (North pole becomes south pole and the south pole becomes the north pole). Magnetic field is the volume in which the magnetism of the magnet can be percieved or detected.
In which direction does a freely suspended current carrying solenoid stay justify?
A current carrying solenoid behaves like a magnet. When suspended freely, it will stay in the north-south direction. On reversing current its polarity will be reversed and so it will turn at 180°.
Can a freely suspended current carrying solenoid stay in any direction what will happen when the direction of current in the circuit change justify your answer?
Answer. No, current carrying solenoid fall freely stay in North – South direction because it behaves as a bar magnet. When current flow through a solenoid is reversed the it direction is also reversed.
What happens when a freely suspended current carrying solenoid is brought near iron fillings?
Explanation: A current-carrying solenoid behaves like a bar magnet. So, a freely suspended current-carrying solenoid also attracts iron objects. when current is not passed the solenoid loses its property of a magnet.
Why does current carrying freely suspended?
When a bar magnet is suspended freely it will come to rest along the direction of the earth’s magnetic field. The magnetic field lines that are produced by the solenoid are similar to that of the bar magnet and behaves like a bar magnet.
Can a freely suspended current carrying solenoid?
A current carrying solenoid behaves like a magnet. When suspended freely it will stay in the north-south direction. On reversing current its polarity will be reversed and so it will turn at 180°.
When a solenoid that is carrying current is freely suspended?
A current-carrying solenoid behaves like a bar magnet. We know that a freely suspended bar magnet aligns itself in the north-south direction. So, a freely suspended current-carrying solenoid also aligns itself in the north-south direction.
Why does a current carrying loop of wire always point in the NS direction when freely suspended?
Answer. Answer: Explanation: Because current carrying loop behaves as a dipole and hence alligns itself in N-S direction.
What effect will there be on a magnetic compass when it is brought near a current carrying solenoid?
When magnetic compass with the north end is brought closer to the 1st end of the solenoid, the needle deflects towards the west, that is, away from the solenoid because the magnetic compass that is pointing in the direction of the earth’s magnetic field, i.e. north- south direction repels with the north pole of current …
Which of the following factors increases decreases the magnetic field strength of a solenoid?
Explanation: The magnetic field of a solenoid is inversely proportional to the length. Hence as the length increases, the magnetic field decreases.
Why does a current carrying freely suspended solenoid rest along a particular direction II state the direction in which it rests?
i) Why does a current carrying, freely suspended solenoid rest along a particular direction? [2] i) Current carrying freely suspended solenoid behaves just like a bar magnet with fixed polarities (North and South) at its ends. Hence, it rest in North-South direction exactly in the same manner as a bar magnet does.
How does a current carrying solenoid?
A current carrying solenoid behaves as an electromagnet. 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.
When the radius of solenoid decreases then magnetic field strength inside the solenoid?
The strength of the magnetic field of solenoid increases with the decrease in number of turns in the solenoid.
What does the divergence of magnetic field lines near?
The divergence of magnetic field lines shows the decrease in the magnetic field’s strength near the solenoid’s ends. The falling degree of closeness of magnetic field lines shows the fall in the magnetic field’s power near and beyond the solenoid’s ends.
What is the nature of the magnetic field inside a solenoid?
The field lines inside the solenoid are in the form of parallel straight lines. This indicates that the magnetic field is the same at all points inside the solenoid. That is, the field is uniform inside the solenoid.
Under what conditions of permanent electromagnet is obtained if a current carrying solenoid is used?
Answer: The conditions to obtain permanent electromagnet as following if a current carrying solenoid is used are (i) The current through the solenoid should be direct current. (ii) The rod inside is made of a magnetic material such as steel.
What is an electromagnet list any?
(a) An electromagnet is a magnet that is created using an electric current, created by electricity. The two uses are: 1)Motors and generators. 2)Transformers.
