No. In order to induce an EMF, the coil and the magnet must be moving in relation to each other.

What happens when a magnet is kept stationary in the middle of the coil?
Not much.
Describe two ways to induce a larger voltage when you move a magnet in a coil of wires?
Speed of movement of coil and the number of turns in the coil
Can you accelerate a stationary charged particle witha magnetic field or an electric field and please explain?
Yes.You must understand that magnetic fields induce electric fields 90 degrees out of phase (or perpendicular) to them, and vice versa.A charged particle will want to move one way or another when put within an electric / magnetic field, because the field will provide a push or pull on that particle in a specific direction.The easiest physical way to view this is with two magnets - imagine a small stationary magnet. If you take another magnet and hold it close to the stationary magnet, the second magnet will be creating a magnetic field that will either push the stationary magnet away or draw it closer. The same thing can be done by creating an electromagnet (push current through a coil of wire near the stationary magnet).
Can you let rotate magnets by themselves to generate electricity?
A magnet rotating inside a coil of wire will induce a current in the wire. Disassemble a bicycle generator and that is what you will find inside, a magnet attached to the input axle surrounded by a coil. The current generated will be alternating current because the magnetic field reverses every 1/2 rotation. Frequency will depend on the speed of the input axle, which is of course dependent on the speed of the bicycle itself.
If a magnet is held close to a coil of wire will it cause current to flow?
Yes, but only if the magnet or the wire are kept moving.

Moving a magnet in and out of a coil of wire produces?
That will induce a voltage across the wire.
When was Magnet's Coil created?
Magnet's Coil was created in 1995.
Can a magnet cause an electric current to flow through a wire?
You obviously cannot more a magnet through a coil in the direction of the current, because the magnet must move, axially, along the length of the coil, while the current moves radially, around the coil. However, if you move a conductor within a coil carrying a d.c. current, then the magnet will induce a voltage into that coil which will oppose the voltage applied to the coil.
How are electromagnets used in mobile phones?
The speakers in a mobile phone are driven by passing AC current through a coil in thepresenceof a static magnet transducing the current into kinetic energy by the speaker coil diaphragm.
What Is cross coil gauge?
This type of gauge has an armature (magnet) that is mounted on the pointer shaft. The armature is surrounded by the stationary cross coils. These three coils are wound across each other

answer me or i will tell every one u suck!!!!!!!
What happens when a bar magnet is thrust into a coil?
When a bar magnet is thrust into a coil, the magnetic field of the magnet will "sweep" across the wire in the coil and induce a voltage in that coil. This is called induction, and if the coil is connected to an external circuit, there will be current flow in that circuit.
What are the different ways to induce current in a coil?
Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.
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
