Is copper the best for making the coil of a magnet?
yes
Thrust a magnet into a coil of wire and the coil?
... exhibits a voltage between its ends. If there is a conductor between the ends of the coil, then a current flows in the coil.
Will Dragging a magnet through a wire coil will create electricity?
Yes. That peculiar action weill create a current in the coil for as long as you keep the magnet moving.
How can the magnetism of a permanent magnet be weakened or removed?
Put it in a coil which has an alternating current in it. The AC current produces a magnetic field in the coil which alternates with the changing voltage. This changes the magnetism of the permanent magnet. Gradually reduce the current in the coil and the permanent magnet will end up unmagnetised.
What is a movable coil?
mic or moving iron coil is instrument type works on ac and dc
Is copper the best for making the coil of a magnet?
yes
When was Magnet's Coil created?
Magnet's Coil was created in 1995.
Is it dangerous to coil a live wire?
It can be if it is wrapped up real tight. You are making a coil and coils produce resistance, and heat.
How are eltromagnets used in generators?
Any time a magnet passes through a coil of copper wire (the electro magnet) it produces electricity. In all reallity, you don't really have an electro magnet in a generator. Since the Coil or(field) is making the electricity instead of using electricity, the electro magnet isn't really a magnet; but more like an "anti-magnet" :)
Can you create electricy from a magnet?
The standard way of generating electricity is moving a wire coil through a magnetic field. So yes
How to adjust air gap on coil on Briggs and stratton motor 5hp model 135202?
The easiest way is to use a standard business card between the coil and the magnet part of the flywheel.
What are the two ways to magnetize a magnet?
thermal - heat the magnet above the Curie Point temperature for the material it is made ofelectromagnetic - use a degaussing coil (a coil driven by AC to keep reversing the field of the magnet), slowly remove the coil from the vicinity of the magnet before turning the power off to the coil
Why does a fan need coil and magnet?
Not all fans do need a coil and magnet - there are hand fans, punkah walla fans belt driven fans (as in your car) and Stirling engine fans that I can think of that do not need a coil or a magnet. It is only electrically driven fans that require a coil and magnet because they work on the principles of electromagnetism.
What is the purpose of the permanent magnet in the moving coil meter?
The purpose of the permanent magnet in the moving coil meter is to measure electrical current. The coil will have a magnetic field which will react to the magnetic field of the permanent magnet. Since opposite poles attract, it will cause for the coil to move.Ê
Which magnet is used to create maximum inductance in coil?
Which magnet is use to create maximum inductance in coil?Read more: Which_magnet_is_use_to_create_maximum_inductance_in_coil
What does the coil do in a microphone?
The coil is basically an electro magnet which is used to move the cone or diaphragm in the headphone. It works like this.... Next to the coil is a permanent magnet, when the currant from your ipod or audio device travels up the cable and into the coil it makes the coil repel the magnet and that in turn moves the diaphragm to produce the sound
In which case will electric current be induced in a coil of wire?
The coil must experience a changing magnetic field in order to have a current induced. You can rotate the coil between the poles of a magnet, or rotate the magnet around the coil.
