What is the effect of eddy current on the metal plate swinging between the poles of the magnet?

The eddy currents act like a brake on the plate, slowing the rate of its movement; if the plate is able to freely swing and is swung through a magnet, it will basically stop dead on the first swing.

What will happen to the current if the magnet and coil were not moving?
I assume you mean in a setup similar to an electrical generator. Here, current is ONLY produced if there is relative movement, between the magnet and coil. Without movement, there will be no current.
Is there a relationship between the size and strength of a magnet?
In reality no. Though the size of a magnet does seem to affect the size of a magnetic field, it is in effect a ratio of volume, and does not change the effect of the magnetic field. The potential magnetism is not affected by size so much as composition of the magnet.
What is the difference between horse shoe magnet and U-shaped magnet ped magnet?
between a horse shoe magnet and u shaped magnet?
What is the difference between a magnet and a rare earth magnet?
A magnet ie. the the ones on your fridge are made by manufactures pushing electrical current through ferrous metals causing them to have magnetic properties. Rare earth magnets are naturally occurring elements that have magnetic properties by themselves.

How a dynamo woks?
Dynamo has constant magnet inside.When movement comes up ,magnet starts turning .And outside of magnet has coiled wire .So this movement of magnet causes electromagnetic effect .Finally current consists with this electomagnetic effect.
How does the strength of the magnet affect the current induced?
The strength of the magnet and its proximity effect the current produced. The magnetic flux density falls quickly so it is important to get close. The stronger the magnet the more lines of flux that pass a point as it moves. Or as something passes by it.
Can electricity cause a magnetic effect?
Yes, a current carrying conductor behaves like a magnet.
Why is magnetism induced into an iron bar placed near a magnet?
A magnetic field induces an electric current. Hence, by placing the iron bar close to the magnet, a current is induced; and so we are, in effect, creating an electromagnet.
Do magnets effect goldfish?
I am not aware of magnets having any effect on goldfish. Maybe a large electro magnet created by passing windings around a tank then applying current through the winding could have an effect but a simple magnet placed on or into a fish tank should have no effect on the fish whatsoever.
What happens if a direct current is put through a coil suspended between the poles of a magnet?
The coil will align itself with the magnetic field (poles) of the magnet.
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.
Where the potential energy the magnet gets in Meissner effect come from?
The Meissner effect is related to an electrical current. The energy comes from getting the current started. Any energy in a magnetic field adds to the effort of getting the current started: this is basically the same as the energy in an inductance.
How can a magnet be used to create an electric current?
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
How was the first man made magnet made?
Hans Oersted, a Dane, was the first to observe the magnetic effect of a current carrying conductor - about 1819.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What magnet is created by an electric current?
Current flow
