What else can I help you with?
Why are cranes in steel works often fitted with electromagnet?
Because they can then lift the steel easily without having to put chains and lifting gear onto it.
What is the meaning of mutual inductance as transformer works on the principle of mutual inductance?
Mutual inductance describes the process by which a changing current in one coil, creates a changing magnetic flux which, when it links with a second coil, induces a changing voltage into that coil.
How fast does an electromagnet have to spin to produce 1megawatt?
A spinning electromagnet does not produce power without other components that you need to specify.
Inductor works in direct current?
Yes, an inductor works with direct current. It is called an electromagnet. Of course, a practical electromagnet has series resistance, otherwise the current in the inductor would increase to the limit of the current/voltage source.
Does frequency effect total inductance?
Inductance is inductance, and is not a function of frequency. Frequency affects reactance, and ultimately impedance, not inductance.
Can an electromagnet be made stronger and stronger without stopping?
yes it can
How do you measure inductance of a coil?
Type your answer here... By use an inductance meter or an inductance bridge
What is inductance comparsion bridge and its application?
It is used to measure the inductance of a coil of unknown inductance.
How do you double the inductance value without double the number of the turns?
In addition to the number if turns, the inductance also depends on the length and diameter of the winding, the pitch (number of turns per inch), and the material of the core if there is one. Search on line and find an empirical formula for the inductance of a finite coil, and then work to tweak the other parameters to alter the inductance as required.
What is inductance measured in?
Inductance is measured in henrys.
How does electromagnet works in transformers?
it is because of major major ang nothing just search it we do not know it
What is an example of a non electromagnet?
A permanent magnet, like a refrigerator magnet, is an example of a non-electromagnet. It produces a magnetic field without the need for an electric current.
