a generator or alternator,if the magnetic is permanent the current produced from the coil will be alternating current ac.
Hydroelectricity or some people call it hydropower. all electricity is the same. hydroelectricity is given its name because of the use of water in the process of making the electricity.
A hard disk is the physical medium information storage device of most computerized systems. It is an actual disk that rotates at high speed. The surface is coated with magnetic material, and data is stored magnetically on the surface. A tiny read/write head on the end of an arm that can move over the surface of the disk does the reading and writing to transfer the information to and from the medium.
The Earth rotates once every 24 hours on its axis (once per day) and revolves around the sun every 365 and 1/4 days (a year). When it is said the the earth rotates, it is meant that the earth is spinning on its axis, which is what causes day and night. However, a revolution is the earth going once around the sun, which is what causes the change of seasons and year. .
In The Online world It Says That, "Because The Earth is tilted and it rotates."
The moon rotates around our planet Earth. The rotation of the Earth refers to the spinning of our planet on its axis.
From changes in its magnetic field, assuming that the magnetic field rotates with the core.
To form the magnetic field that rotates the motor. :)
yes all the other planets have magnetic fields except venus because it rotates to slowly
The stator is the stationary winding assembly that makes the magnetic field inside the alternator. It is this magnetic field that the armature rotates in generating the electricity.
It uses a magnetic needle to point to the earth's magnetic North Pole. The only other type of compass used is a gyro-compass. This uses a wheel which rotates parallel with the earth's rotation.
A sine wave is, theoretically at least, the naturally-generated voltage produced by any rotating machine. This is because the voltage induced into a conductor that rotates within a magnetic field is proportional to the sine of the angle at which the conductor cuts the magnetic flux. In practise, a perfect sine wave is not produced in most practical machines, but it is close enough for practical purposes.
The shaft of an AC induction motor rotates because of the torque created by the interaction between the magnetic field of the stator and the magnetic field of the rotor.
The inner magama rotates creating earths magnetic field which stops solar wind
The earth rotates on its axis. One end of the axis is called the north pole (where the earth rotates counterclockwise around the pole) and the other end is called the south pole (where it rotates clockwise).
1) Rotating armature alternator, rotates in stationary magnetic field. 2) Rotating field alternator, the magnetic field is rotating.
It rotates the rotor. Torque is produced by the magnetic force on the current induced in the squirrel cage. This magnetic force acts as torque on the rotor as a tangential force that makes it spin.
The Earth rotates every hour and it takes 365.25 days to go around the sun. the earth rotates with the magnetic poles and it uses gravity to go around the sun
