Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
This process is known as electromagnetic induction. When a magnet moves through a loop of wire or when the loop moves through a magnetic field, it induces a current in the wire due to the changing magnetic field. This phenomenon is described by Faraday's law of electromagnetic induction.
Permanent magnets do not produce electric currents on their own. However, when a permanent magnet moves near a closed loop of wire or coil, it can induce an electric current in the wire due to electromagnetic induction.
Moving a magnet through a loop of wire creates an electric current in the wire. This phenomenon is known as electromagnetic induction, discovered by Michael Faraday in the 19th century. It forms the basis for the working of generators and transformers.
A current is induced in the conductor by the moving magnetic field (relative to the wire, the field is moving) I guess induction might be the term you are looking for.Another AnswerMoving a magnet through a loop of wire will induce a voltage, not a current, into a coil. If the coil forms a closed loop, then a current will result. But it's a voltage that's being induced, not a current -the current is merely the result of that voltage.
Moving a magnet quickly in and out of a coil of wire induces an electric current in the wire due to electromagnetic induction. The changing magnetic field created by the moving magnet induces a current flow in the wire loop according to Faraday's law of electromagnetic induction.
The magnetic field generated by the magnet would also stop, causing the induced current in the loop to cease. This would result in a decrease in electromagnetic induction and the loop would have no current running through it.

why, if the same current flows in a wire coil and a single loop, the magnetic field inside the coil stronger than the field inside the loop
A looped wire would have a stronger magnetic field because a looped wire is closer to the magnet all the way aroud.

A note about terminology - magnetic energy is the energy stored in a magnetic field. I have never heard of magnetic power. However, I assume you are asking how to get electrical power from magnetic phenomena. The way this works is directly from maxwell's equations. Faraday's law says that the rate of change of flux through a loop (field through loop times area of loop) is proportional to the electric field around that loop, which is proportional to the current, if the loop is a conductor. The generator works by spinning a permanent magnet near a loop of wire. As the magnet spins, it induces current in the loop of wire, which can then be made to do useful work. A note about energy conservation: when the current in the loop is induced, it is always in such a way as to attract the spinning magnet, so the external agent has to do work to resist this.
When the magnetic flux (field) intersecting a loop of wire changes, a voltage is induced between the ends of the loop. If a resistor is connected between the ends, a current flows and power is produced, but in this case a force is needed to move the magnet, and this provides the power.
