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.

What type of current is used in an electirc motor?
Well that depends on the type of motor. DC motors use direct current DC and induction motors use alternation current AC.
What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
Why DC cannot produce induction?
DC is uni-directional so it cant produce induction.
In Electromagnetic Induction would a series of magnets moving in one direction-like on a wheel- with a coil of wire on top of the wheel beside the magnets induce current and is it AC or DC?
it is dc
What is a DC generator the same as?
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.
Is induction voltage ac or dc current?
Induction occurs only with alternating current.
What type of current is used in an electirc motor?
Well that depends on the type of motor. DC motors use direct current DC and induction motors use alternation current AC.
What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
What happens if dc is given to induction motor?
It will draw a heavy current and coils will be brunt.
Why DC motor current ripple?
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".
Why DC cannot produce induction?
DC is uni-directional so it cant produce induction.
What instruments do AC to dc current use?
I would assume that you mean what devices do you use to convert ac current to dc current?The answer is Diodes.seediode-bridge
In Electromagnetic Induction would a series of magnets moving in one direction-like on a wheel- with a coil of wire on top of the wheel beside the magnets induce current and is it AC or DC?
it is dc
Does a car use DC or AC power?
the car use dc current dear
Where do you use DC current?
DC current is mainly used in electronic component i.e. computer etc
Can you tell me The working of DC motor?
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.
Which type of current does a dc motor use?
dc stands for direct current. This can be obtained from a battery or a rectified ac (alternating current ) supply.
