Induced voltage happens through induction. When a wire goes through a magnetic field a voltage is induced across its ends.
The basic equation is Ampere's law: Curl E = dB/dt at every point, where E is the electric field and B the magnetic flux density.
For a loop of wire Stokes's theorem can be applied to this: Integral E.dl = d/dt of the surface integral of B.dS which says that the induced voltage along the loop equals the rate of change of the magnetic flux linking the area of the loop.
Well that depends on the type of motor. DC motors use direct current DC and induction motors use alternation current AC.
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
DC is uni-directional so it cant produce induction.
it is dc
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
Induction occurs only with alternating current.

It will draw a heavy current and coils will be brunt.
DC is uni-directional so it cant produce induction.
The induction of a DC motor while rotation lead to a non continuid current. This AC part of the DC csupply current is called ripple current. You can measure this and see if the motor is moving and also you can count the ripple per second and have the motor speed "RMS".
I would assume that you mean what devices do you use to convert ac current to dc current?The answer is Diodes.seediode-bridge
the car use dc current dear
it is dc
DC current is mainly used in electronic component i.e. computer etc
A DC motor works on the principle of Faraday's law of electromagnetic induction, i.e., when a current carrying conductor is placed in a magnetic field, it experiences a force applied on it.
