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.
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.
How is a solenoid similar to a magnet?
A solenoid acts like a magnet when an electrical current is sent through the coil. A permanent magnet is magnetic all the time. Therefore, they are similar when both act like a magnet, but not when the solenoid is turned off.
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 deflection in the galvanometer reversed when the magnet is moved in and out in a solenoid?
When the magnet is moved into the solenoid, the change in magnetic field induces an electric current in the solenoid. This induced current then creates a magnetic field that opposes the initial magnetic field created by the permanent magnet. This opposing magnetic field causes the galvanometer deflection to be reversed.
How does the magnetic field outside a solenoid behave similarly to that of a bar magnet?
The magnetic field outside a solenoid behaves similarly to that of a bar magnet because both have field lines that form a pattern resembling that of a bar magnet, with the field lines curving around from one end to the other.
How is solenoid a magnet?
A Solenoid is an electro-magnet. It has coils of wire, usually copper. When an electric field is applied to the coils of wire, an magnetic field is generated. This magnetic field attracts a steel or iron segment on the switch and activates the switch.
How is earth's magnetic field similar to that of a magnet?
electric current in a solenoid coil
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.
How is earths magnetic field similar to that of a bar magnet?
electric current in a solenoid coil
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.
How can you use a solenoid to make a temporal magnet?
Passing it through a coil that has a DC current through it. The DC current creates a field which allows the realignment of electrons in the solenoid, allowing it to have temporary magnetic properties. Passing an AC current through the coil would demagnetize the solenoid.
