What is the strength and direction of the magnetic field outside of a solenoid?
The strength of the magnetic field outside of a solenoid is weak and the direction is similar to that of a bar magnet, flowing from the north pole to the south pole.
How a solenoid may be used to demagnatise a bar magnet?
To demagnetize a bar magnet using a solenoid, the magnet can be placed inside a solenoid and the current can be gradually decreased to zero. This process disrupts the alignment of magnetic domains within the magnet, leading to demagnetization. The alternating current can also be used for more effective demagnetization.
What kind of magnet has the same magnetic field as the long coil of wire?
A solenoid magnet, which is a long coil of wire wrapped around a ferromagnetic core, has a similar magnetic field to that of a bar magnet. This is because the magnetic field created by the current flowing through the wire generates a magnetic field similar to that of a bar magnet.
How can be solenoid be converted into an electromagnet?
A solenoid can be converted into an electromagnet by running an electric current through the coil of wire. The current creates a magnetic field around the coil, turning the solenoid into a magnet. When the current is turned off, the solenoid no longer functions as a magnet.
Which kind of magnet has the same magnetic field as the long coil of wire?
A solenoid, which is a long coil of wire, produces a magnetic field similar to that of a bar magnet when a current passes through it. The magnetic field produced by a solenoid is confined within the coil and has north and south poles along its axis.
What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?
A solenoid typically produces a magnetic field similar to that of a bar magnet. The magnetic field lines form loops around the solenoid, making it closely resemble a bar magnet with north and south poles at either end.

What does the magnetic field in a solenoid resemble?
The magnetic field in a solenoid resembles the field of a bar magnet, with field lines running parallel to the axis inside the solenoid and forming loops around the outside.
How does a solenoid act as a magnet?
When current is passed through a solenoid coil, magnetic field produced due to each turn of solenoid coil is in the same direction. As a result the resultant magnetic field is very strong and uniform. The field lines inside the solenoid are in the form of parallel straight lines along the axis of solenoid. Thus, the solenoid behaves like a bar magnet.
Why is the magnetic field produced by a cylindrical solenoid is similar to a cylindrical permanent magnet?
Simple Answer:The shape of the magnetic field of a uniformly wound solenoid is very nearly identical to the field produced by a uniformly magnetized permanent magnet with the same physical shape as the solenoid.For the Experts:This is a consequence of the mathematical equivalence of the source of the magnetic field as created by a current and the source of a magnetic field as created by the curl of the magnetization density of permanent magnet.
