It is the flow of ELECTRICITY that makes the field in a coil. Therefore a coil of any conductor will make a field. Silver is a conductor.

How do you produce a uniform magnetic field?
To make a long story short I wanna mention the name of several methods to make uniform dc magnetic fields: Using the space inside a solenoid Using the Helmholtz coil Using the Maxwell coil as all of these configurations take benefits of the phenomena in which current produces a magnetic field, the amplitude of the magnetic field would be easily controlled by control upon the current passes the loops of windings.
How is mechanical energy turned into electrical energy?
A wire moving in a magnetic fields creates electric current. Moving a coil of wire into a magnetic field creates a voltage across the ends of the coil. The voltage equals the number of turns times the rate of change of magnetic flux. If a resistor is placed across the coil and it is moved into the field again, current flows in the resistor, creating energy in the form of heat. At the same time a force will be needed to push the coil into the field, thus providing the mechanical energy for this process. Electrical engineers have to understand how to make the process as efficient as possible.

How do you make a sentence for magnetic field?
The magnetic field of the Earth protects us from cosmic radiation.
How is an electromgnet and a bar magnet different?
The bar magnet is what is termed a permanent magnet . This means that it is "always on" and can be used to do things like pick up paper clips. The electromagnet is created by winding a coil of wire about a ferromagnetic core and running a direct current through that coil. Only when the current is flowing will the electromagnet be operating. With the current switched off, the magnetic field around the coil of wire disappears, and the power of the electromagnetic disappears as well.There are some "fine points" associated with a further extension of this post, but the basic answer to the question is as written.A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
How does an electric coil works?
when u give supply to a coil then a current will be passed through it .naturally a magnetic field is produced around the c.c.c(current carrying conductor). when u make more turns in the same direction the whole magnetic field will be stronger than that of a wire has. andby lenz's law there will be an opposition to the changing current in a coil due to the change in magnetic field produced

How does a current in the coil make the straw pointer move?
1.Current in the coil produces a magnetic fieldalso accept "the coil becomes an electromagnet"or "the coil is magnetized"2.The magnet is repelled or attractedalso accept "the field or coil exerts a force on themagnet"
In an electromagnet the magnetic force increase as increase?
Adding more coils will make the magnetic field stronger. Magnetic field increases.
What is th answer to an electric current can be generated by moving a wire coil in a magnetic?
Studying your words in fine detail, I still can't make out what the question is. It may be as simple as adding the word "field" at the end, after "magnetic".
How do you make eictricry?
You can make Electricity by various means. Mechanically, by rotating a magnetic field near a coil, (generators.) Chemically, By using metals, acids and alkalies in a container, (battery.)
Could you make a generator by mounting permanent magnets on a rotating shaft and keeping the coil stationary?
Yes, only relative motion between the coil and the magnetic field is important.

What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
How do the vibrations from the voice coil in a speaker make distinguishable noises?
Speakers generate distinguishable noises, or sounds, by converting fluctuations in electric current in the voice coil into fluctuations in magnetic field. That generated magnetic field, being in the presence of a larger magnetic field, creates mechanical fluctuations in the position of the voice coil. Since the voice coil is mechanically coupled to the cone, the cone transfers those fluctuations to the cone. The cone, then, couples those fluctuations into fluctuations in air pressure, which our ears interpret as sound waves. Its not really any different than the magnetic fields in a motor, except that we are generating fluctuating, vibrational energy, instead of rotational energy.
