What does the magnetic field in a solenoid resemble?
a bar magnet
What does the Earths magnetic field resemble?
That of bar magnet..
What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?
The magnetic field produced by electric current in a solenoid coil is similar to that of a bar magnet.
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.
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 is earths magnetic field similar to that of a bar magnet?
electric current in a solenoid coil
What are the similarities and differences between a solenoid and a bar magnet?
DIFFERENCE: a bar magnet is a permanent magnet where as solenoid is a electromagnet so it acts as a magnet only when electricity is passed through it. SIMILARITIES: they both act as magnets and both have a similar magnetic field.
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 a solenoid may be used to demagnatise a bar magnet?
Heating a bar magnet with solenoid demagnatise it.
What does a magnet do in the television?
Usually there is no ferrous magnet within the TV - i.e a permenant magnet. Rather a solenoid is used to generate a changing magnetic field. Simply put, the magnetic field is used to focus the cathode ray that creates the image on your television's screen.
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.
