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What would happen to the voltage and the magnet is withdrawn from the coil?
When the magnet is withdrawn from the coil, the magnetic field within the coil will decrease, inducing a voltage in the coil. This induced voltage will create a current in the coil that flows in such a way as to try to maintain the original magnetic field.
Why do you get a voltage reading when the switch is turned off?
When the switch is off, there can still be a voltage reading if there is a constant power source connected to the circuit. This can be due to factors such as leakage currents, residual charge in capacitors, or electromagnetic induction in nearby wires inducing a voltage in the circuit.
How can 12 volts from a battery be changed to 40000 volts for ignition?
To change 12 volts from a battery to 40,000 volts for ignition, a device called a transformer or an ignition coil is used. The ignition coil steps up the low voltage from the battery to a much higher voltage through electromagnetic induction. When the coil is energized, it creates a magnetic field that collapses when the current is interrupted, inducing a high voltage in the secondary winding, which can generate the necessary voltage for igniting fuel. This high voltage is then delivered to the spark plug to create a spark for ignition.
What rhymes with inducing?
reducing
An inductor opposes a change in?
current flowing through it by inducing a voltage that creates a magnetic field, which stores energy. This property of inductors results in opposition to changes in current, which is described by Faraday's law of electromagnetic induction.
How does magnetic tachometer work?
A magnetic tachometer works by using a rotating magnet on the shaft of the device being measured and a stationary magnetic pickup sensor. As the shaft rotates, the magnet passes by the sensor, inducing a voltage that is directly proportional to the speed of rotation. This voltage signal is then converted into a numerical value to provide the speed measurement.
What chemical is responsible for inducing sleep in the human body?
The chemical responsible for inducing sleep in the human body is called melatonin.
In what two ways is it possible to generate a higher voltage in a moving conductor?
Higher voltage can be achieved in a moving conductor by increasing the strength of the magnetic field it moves through or by increasing the speed at which it moves through the magnetic field. Both of these factors contribute to inducing a greater electromotive force (emf) in the conductor, resulting in a higher voltage output.
Which is the method of avoiding phagocytosis?
Inducing endocytosis
How a antena convert waves into current?
An antenna converts electromagnetic waves, such as radio or microwave frequencies, into electrical currents by inducing voltage across its length as the waves interact with its conductive elements. This induced voltage generates an alternating current in the antenna that can be captured and processed by electronic circuits to extract information or power. The design of the antenna, including its length and shape, determines its efficiency at converting waves into current.
What are synonyms of motive?
Inspiring, encouraging, stimulating or inducing.
