Hello everyone,

I'm doing research on solenoid design for satellite magnetic torquers. I've come across a couple of papers that mention "Loney's Solenoid". Does anyone know who Loney is/was and where I can find the details on "Loney's Solenoid"? Thanks.

This is my first post. Sorry in advance if this post is categorised or has broken any forum conventions.

Thanks!

Hello CanEngineer! Welcome to PF! :smile:

"This device is used when a highly uniform magnetic field, along a prefixed region, is required. Its simplest configuration consists of a main coil and two so-called correcting, or shim, coils."​

See http://www.piers.org/piers2k4Pisa/session_62/62_01.pdf for description and diagram. :wink:
 

FAQ: What is the Design of Loney's Solenoid for Satellite Magnetic Torquers?

What is Loney's Solenoid?

Loney's Solenoid is a type of electromagnet named after its inventor, William Loney. It is a cylindrical coil of wire with an electric current passing through it, which creates a magnetic field. This magnetic field is used in various applications, such as in motors, generators, and actuators.

How does Loney's Solenoid work?

The principle behind Loney's Solenoid is based on the right-hand rule, where the direction of the magnetic field created by the current in the wire is perpendicular to the direction of the current and can be determined using the thumb, index, and middle fingers of the right hand. The magnetic field created by the solenoid can be amplified by adding an iron core inside the coil.

What are the differences between Loney's Solenoid and other types of solenoids?

Loney's Solenoid is different from other types of solenoids in terms of its shape and size. It is typically longer and narrower compared to other solenoids, and it has a larger number of turns of wire, which results in a stronger magnetic field. It also has a slower response time compared to other solenoids due to its larger size.

What are the practical applications of Loney's Solenoid?

Loney's Solenoid has a wide range of practical applications, including in electrical and mechanical devices such as relays, switches, valves, and locks. It is also used in medical equipment, such as MRI machines, and in industrial equipment, such as conveyor belts and sorting machines.

What are the advantages of using Loney's Solenoid?

One of the main advantages of Loney's Solenoid is its ability to produce a strong and uniform magnetic field, making it ideal for use in various electromechanical devices. It is also a simple and cost-effective design, making it widely used in different industries. Additionally, it has a long lifespan and low maintenance requirements.
