The solenoid principle. A coil of wire is connected to some sort of electric current.
What else can I help you with?
Direct electric current cannot be used to operate A. Electric motors B. Electric heaters C. Electromagnets D. Transformers?
Direct electric current cannot be used to operate D. Transformers.
Devices that uses electromagnet?
Solenoid valves, magnetic contactors, motors.
What devices instrument that use electromagnets to operate?
Some devices that use electromagnets to operate include MRI machines, transformers, electric motors, and loudspeakers. Electromagnets are used in these devices to generate magnetic fields that can be controlled and manipulated to perform specific functions.
Why DC motors and DC generators are commonly known as DC machines?
because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.
What are the uses of induction coils?
1. Transformer 2. DC/ AC Motors 3. Solenoid valves 4. Contactors/ Relays 5. Amplifiers
Example of transformer lap winding diagram?
'Lap windings' apply to motors, not transformers.
What is the function of contactor?
A contactor is used like a switch. It is used to open and close the circuit it is in series with by electrically energizing and de-energizing the holding coil of the contactor. By having this adaptability the circuit can be remotely operated from a distance and the operator does not have to be in close proximity to the circuit. Contactors are used to remotely operate banks of lighting and of course the contactor is used for motor control. On contactors that control motors an additional overload block is added to the bottom side of the contactor to protect the motors if they get into an over load condition. The N.C. contacts in the overload block will open and the holding coil of the contactor will de-energize and drop the motor off line.
How are motors and magnets alike?
Magnets and electric motors are similar in that they both produce magnetic fields.
What has the author Leonard R Anderson written?
Leonard R. Anderson has written: 'Electric machines and transformers' -- subject(s): Electric machinery, Electric motors, Electric transformers
List a following devices that use electromagnetism to work?
Electric motors Speakers MRI machines Transformers Microwaves Doorbells Generators
What is the difference between contactor transformer?
Relays and Contactors are electromagnetic switches. The onlydifference is that relays are usually used for low voltageapplications while contactors are used for higher voltageapplication. Contactors usually have Overload protection.Some examples that I can give (at least in Manufacturing ofIndustrial Control panels):-Relays are use as electromagnetic switches to controlcertain parts of a circuit (low voltage application). Abetter example would be such as if you want your circuit tosound a horn when a certain abnormality is happening at acertain period of time, then depending how you set up yourcircuit, a specific relay will either open or close and youhorn will start making the sound.-Contactors can be used for example, to start motors or anumber of motors that require a higher voltage in order forthe motor or motors start working. In the example that Ijust gave, contactors work as starters.
What are city motors used for?
City motors are used for pumping water throughout the city. Without city motors, water would not flow to households. It's important to remember that city motors require maintenance to operate.
