dynamo works on the principle of induced current produced due to change in magnetic field or on lenz law
as u know dynamo is rotated by mechanical work the no. of magnetic field line passing through the area changes with time which in turn induces current in dynamo which can b used to glow light bulb

there is a property in copper and many other metals if a magnet is rotated around them they produce electricity. In the same way a dynamo works. There is a coil of wire placed in the middle. The rotation moves the magnets in the dynamo this produces current in the coil which is then taken through a wire to be used.

Electro-magnetism is correct, more precisely using Faraday's principal of electro-magnetism. Michael Faraday first observed that when a conductor moves perpendicular to a magnetic field a current is induced in the conductor.
A dynamo is just another term for a generator and the principal is basic a permanent magnet is made to spin inside a conductive coil or group of coils to produce a current. The mechanical energy is used to drive to the magnet (armature), which induces a current in the wire coils.

Dynamo is the best team in the MLS and America took it more as a preseason game but expect Dynamo to make it to the final. They are a great team the best in the USA

First:
Dynamo:
------------
it is a device tht is used to convert mechanical energy into electrical energy
Second:
How it transforms:
------------------------
When its coil rotates (mechanism) in a magnetic field such that it cuts across the flux lines, so an induced E.M.F is produced (electricity) which depend on the angle of rotation
i hopr u got ur point from my explanation

By rotating coils of insulated wire in a magnetic field; the opposite of an electric motor.
