How does modern technology use electromagnets?

There are various uses of electromagnets in modern technology.

The first and very recent use of electromagnet is magnetic levitation train. Here strong electromagnets are used by which the magnetic levitation of train and its propulsion become possible.

The second use of electromagnet is lifting heavy plates of magnetic metals from shore to the ship.

The electromagnets are also used in various kinds of electric devices like speakers,generators,motors and hard disk drivers etc. In electric bells,the electromagnetic coils are used which helps in striking the bell.

The electromagnets are also used in casa of cyclotron. In case of cyclotron,strong electromagnetic dees are present which plays a crucial role in accelerating the charged particle.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to
