Do the induced voltage increase in a transformer when the magnetic field strength increase?
Yes, the more voltage you put in the more you get out. If the transformer is a 2 - 1 ratio and you put 240 in you get 120 out and when you put 480 in you get 240 out. Magnetic field strength and voltage have a direct relationship.

The field strength is actually a function of current, although as you say, increasing the voltage will increase the current hence the magnetic field.
What else can I help you with?
What is induced by the rapid alternation of a magnetic field?
you would induce voltage therefore chanfing the magnetic field
What is difference between induced voltage and induced current?
Just as a current flowing through a wire will produce a magnetic field, so a wire moving through a magnetic field will have a current flowing through it. This is called electromagnetic induction and the current in the wire is called induced current. A stationary wire in the presence of a changing magnetic field also has an induced current. A changing magnetic field can be produced either by moving a magnet near to the stationary wire or by using alternating current. A stationary wire in a magnetic field which is not changing will have no current induced in it. You will sometimes see this effect described as induced voltage. Strictly speaking, you will only get an induced current in the wire if it is part of a complete circuit. A wire which is unconnected at both ends will have a difference in voltage between the ends (a potential difference) but current can only flow when the wire is in a circuit. Induced current is used in electricity generation and transformers.Another AnswerThere is no such thing as an 'induced current', only an 'induced voltage'. Current will flow only if the conductor into which the voltage is induced forms part of a closed circuit.
How the process of change in magnetic flux causes induced emf?
According to Faraday's laws of electromagnetic induction, whenever a varving flux link with a conductor an emf is induced.
Moving a conductor through a magnetic field a voltage is induced in the conductor is called what type of induction?
Moving a conductor through a magnetic field will produce alternatinc current (AC).
What is definition of paramagnetic and dimagnetic materials?
A dimagnetic material produces a magnetic field that opposes an external field. A paramagnetic materia, on the other hand, produces a magnetic field that increases an external field. Dimagnetism and paramagnetism are induced when an object is placed in a magnetic field.
Is the size of the voltage induced in a coil through which a megnet moves affected by the strength of the magnet?
Yes, the induced voltage in a coil is affected by the strength of the magnet. A stronger magnetic field will generally result in a higher induced voltage in the coil, due to the increased rate of change of magnetic flux.
What is the relationship between the induced voltage in a two-coil system and the magnetic field strength?
The induced voltage in a two-coil system is directly proportional to the magnetic field strength. As the magnetic field strength increases, the induced voltage in the coils also increases.
How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
What is saturation in magnetic materials?
Saturation in magnetic materials is the point at which the material can no longer be magnetized further, even with an increase in magnetic field strength. At saturation, all magnetic moments in the material are aligned in the direction of the magnetic field, and no additional magnetic flux can be induced.
How is induced current in a wire generated and what factors influence its strength?
Induced current in a wire is generated when there is a change in magnetic field around the wire. Factors that influence the strength of the induced current include the rate of change of the magnetic field, the number of turns in the wire, and the material of the wire.
What would not affect the strength of an induced current?
The strength of an induced current is not affected by the resistance of the circuit it flows through. The factors that affect the strength of an induced current are the rate of change of magnetic flux, the number of loops in the coil, and the material of the coil.
How is induced current in a loop affected by changes in magnetic field strength?
The induced current in a loop is directly affected by changes in magnetic field strength. When the magnetic field strength increases or decreases, it causes a change in the magnetic flux passing through the loop, which in turn induces an electric current in the loop according to Faraday's law of electromagnetic induction.
Is it appropriate to use dc supply in a transformer?
Not usually. Transformers require a varying magnetic field, which is induced by AC voltage.
Can the strength of natural magnets be increased?
The strength of natural magnets be increased in various ways. Artificial magnetism can be induced so as to increase magnetism.
What is meant by transformer charging?
Most likely this is referring to the initial inrush that occurs when a transformer is energized. The core of a transformer is designed for a specific magnetic field strength; When a transformer is switched into a circuit, it usually will not be switched at exactly a voltage peak. When the voltage is at its' peak, the induced magnetic field will be at zero. If the switching occurs at a voltage zero, the magnetic field strength will attempt to climb to double the designed value; since the transformer core is not generally oversized to this degree, it will saturate. This causes large inflows of current to the transformer, and shows up as even harmonics (mainly second harmonics) in the current waveform. This settles out within a few seconds (generally) to a small energizing current, usually less than 1% of the transformer's rated current.
What are the three ways in which the strength of induced emf in electric generator can be increased?
Increasing the number of turns in the coil to enhance the magnetic flux linkage. Using stronger magnets or increasing the speed of rotation to boost the magnetic field strength. Utilizing a core with higher magnetic permeability to enhance the flux density and, consequently, the induced emf.
What actions will not increase the electric current induced in a wire?
Actions that will not increase the electric current induced in a wire include changing the wire's length or material, adjusting the wire's temperature, or altering the wire's tension. Inducing a current involves changing the magnetic field around the wire, so actions that do not affect this magnetic field will not increase the induced current.
