When the electric current is transferred through the solenoid, it gives the magnetic lines of forces similar to a bar magnet, so BAR MAGNET is the right answer. Here one of the solenoids acts as the magnetic north pole, and solenoids at the other end act as the magnetic south pole.
What happens when electric current is passed through a solenoid?
A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. As a result the solenoid acts as a temporary magnet. When the current stops passing it loses its magnetism.
When electric current is passed through the solenoid it shows magnetic lines of force similar to <UNK>?
When current is passed through a solenoid, the magnetic fields act almost like that of a bar magnet. One end acts as the magnetic north pole, and the other end acts as the magnetic south pole.
When current is passing through solenoid then it behaves like?
solenoid behaves like a bar magnet when a current is passed through it. It’s one end of behaves as Magnetic North Pole and the other end as Magnetic South Pole. … If the magnet is attracted, the end is south end of the solenoid.
Why does current flow in a solenoid?
Summary. A solenoid is a coil of wire with electric current flowing through it, giving it north and south magnetic poles and a magnetic field. Using more turns of wire in the coil or more current increases the strength of the solenoid’s magnetic field.
When current is passed in a solenoid the magnetic field inside the solenoid must?
-Inside a solenoid the magnetic field is directly proportional to both the applied current and the number of turns per unit length. The field inside the solenoid is constant.
When electric current is passed through acidulated water of water takes place?
When electric current is passed through acidulated electrolysis of water takes place. Explanation: When an electric current is passed through acidulated water, it will produce electrolysis. During this process, water is decomposed into hydrogen and oxygen.
Which of the following does not use magnetic effect of electric current?
What are the heating effects of electric current?
The heating effect of the electric current is also known as the thermal effect of the electric current. When an electric current tends to flow in the conductor, electrical energy tends to get expended to overcome the frictional resistance between the molecules and the electrons in the wire.
Is heating effect of electric current observed in electric motor?
It converts electrical energy into mechanical energy. … Thus, it is clear that the heating effect of electric current is not observed in the functioning of an electric motor. Hence, Option (C) is correct.
When current is parallel to magnetic field?
Force on a current-carrying wire that is parallel to magnetic field will be zero. This is because the magnitude of force depends on the sin of the angle between the direction of current and the direction of magnetic field, so if the current carrying wire is held parallel to the magnetic field, the force will be zero.
Where is the magnetic field of a bar magnet the strongest?
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)
