What is the center of an electromagnet called when it is surrounded by coils of wire?
In a transformer it is known as the transformer core.
If you doubled the number of coils and doubled the voltage what would be the increase in magnetic strength?
well if you doubled the coils it would be pie times the amount of voltage in the current squared
The ratio of coils on the input side of a transformer to coils on the output side is the ratio of the input voltage to the output voltage?
I think you mean 'turns' rather than 'coils' (a coil is made up of a number of turns). The answer is that, yes, the turns ratio is the same as the voltage ratio, for an ideal transformer.
What is the function of restraining coils in differential relay?
Restraining coils are also called as bias coils. Due to the difference in the magnetizing currents of the upper and lower current transformers the current through the operating coil will not be zero even under normal loading conditions or external fault conditions. therefore to provide stability on external faults bias coils are provided. To obtain the required amount of biasing a suitable ratio of the biasing coils with restraining coils to be provided.
Write any two factors on which strength of induced current depends?
The strength of induced current depends on the number of coils of the cunductor and the strength of the magnet.
What is the effect of increasing the number of coils of wire wrapped around the core of an electromagnet?
This causes the power of the electromagnet to be increased.
What effect does decreasing the number of coils around the nail have on the strength of the electromagnet?
Decreasing the number of coils reduces the strength of the magnet.
In an electromagnet the magnetic force increase as increase?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
How the magnetic field of an electromagnet defends on the current and the number of coils?
The magnetic field of an electromagnet is directly proportional to both the current passing through its coils and the number of coils. Increasing either the current or the number of coils will result in a stronger magnetic field, while decreasing them will weaken the magnetic field. This relationship is described by Ampere's law and the concept of magnetic flux.
How can you make a electromagnetic?
You can make an electromagnet stronger by increasing the number of loops in the coil or by passing more electricity through the coils or by chaging the core to a be replaced by a better conductor.
Is you true the magnetic field around an electromagnet can be made stronger by increasing current or decreasing the number of coils around the iron core?
No, you is false. Increasing current does it, but the number of turns in the coilalso must increase if you want to increase the magnetic field that way.
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
How do you calculate pitch using length and number of coils?
Number of coils of what? Maybe wire in an electromagnet? Please resubmit the question with more detail.
How can you increase the strength of a electromagnet?
More currents, or more loops.
What is the effect of adding more coils of wire to an electromagnetic?
Increasing the coils will increase the strength of the magnetic field.
Would spinning the loops on an electromagnet make it stronger?
Yes, if you increase the number of coils or loops in an electromagnet, it's power increases.
How do you make an electromagnet weak?
reducing the number of coils around the core or by reducing the current in an electromagnet, will cause the magnetic power to weaken.
