Can a Loop of Wire Be a Solenoid?

In summary, a loop of wire can be a solenoid by passing an electric current through it, creating a magnetic field. Solenoids have various uses in electromagnets, motors, and electronic devices. They cannot function without an electric current, but can retain some magnetic properties even when turned off. There is no specific limit to the size of a solenoid, but larger ones may require more current and can be affected by factors such as wire material and coil turns.

Can a loop of wire be considered a solenoid, which has been turned once?

-Thanks.

yes, you can consider it as a solenoid with one loop. but it would practically not be a solenoid, as it won't have uniform magnetic field inside it.
 
  • #3
it is a solenoid but an extremely non ideal one
for ideal solenoid ... length >> radius of any loop

but mostly any1 would call is just a loop instead of solenoid
 

FAQ: Can a Loop of Wire Be a Solenoid?

Can a loop of wire be a solenoid?

Yes, a loop of wire can be a solenoid. A solenoid is simply a coil of wire that produces a magnetic field when an electric current is passed through it. Therefore, any loop of wire with an electric current passing through it can be considered a solenoid.

How does a loop of wire become a solenoid?

A loop of wire becomes a solenoid when an electric current is passed through it. The electric current creates a magnetic field around the wire, which is concentrated in the center of the loop. This creates a strong magnetic field, similar to that of a bar magnet.

What is the purpose of a solenoid?

Solenoids have a variety of uses, including in electromagnets, motors, generators, and electronic devices such as speakers and doorbells. They are also commonly used in industrial and manufacturing processes, such as in valves and switches.

Can a loop of wire be a solenoid without an electric current?

No, a loop of wire cannot be a solenoid without an electric current. The electric current is what creates the magnetic field and without it, there would be no magnetic field and therefore no solenoid. However, a solenoid can retain some of its magnetic properties even after the current is turned off.

Is there a limit to the size of a solenoid made from a loop of wire?

There is no specific limit to the size of a solenoid made from a loop of wire. However, as the size increases, the strength of the magnetic field produced may decrease. Additionally, larger solenoids may require more electric current to produce a strong magnetic field. Other factors such as the material of the wire and the number of turns in the coil can also affect the size and strength of the solenoid.
