How can you increase the amount of electric current produce by generator?
To increase the amount of electric current produced by a generator, you can increase the rotational speed of the generator, increase the strength of the magnetic field within the generator, or increase the number of turns in the generator coils. These methods will result in a higher induced voltage and therefore a higher electric current output.
How is the induced surface charge affected by external electric fields?
The induced surface charge is influenced by external electric fields. When an external electric field is applied, it can attract or repel charges on the surface, causing the distribution of charges to change. This can result in an increase or decrease in the induced surface charge depending on the direction and strength of the external electric 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 direction of the induced electric field?
The direction of the induced electric field is perpendicular to the change in magnetic field.
How was current produce or induced?
Current can be induced in a conductor through electromagnetic induction, where a changing magnetic field causes a flow of electric current. This can be achieved by moving a magnet near a conductor or by varying the current in one nearby. Alternatively, current can be produced by a voltage source such as a battery or generator that creates a potential difference to drive the flow of electrons.

How is the induced voltage of separately excited dc generator affected if the exciting current is reduced?
In a separately excited DC generator, the induced voltage is directly related to the magnetic field strength produced by the field winding, which is influenced by the exciting current. If the exciting current is reduced, the magnetic field strength decreases, leading to a reduction in the induced voltage. Consequently, the output voltage of the generator will decrease as the field strength diminishes, assuming all other factors remain constant.
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.

This can result in an increase or decrease in the induced surface charge depending on the direction and strength of the external electric field.
What is the factors determining induced emf in dc machine?
The factors determining induced electromotive force (emf) in a DC machine include the strength of the magnetic field, the number of turns in the coil, the speed of rotation of the armature, and the angle of the coil relative to the magnetic field lines. The induced emf is directly proportional to the magnetic field strength, the number of turns in the coil, and the speed of rotation, while it is also affected by the angle of the coil in relation to the magnetic field. These factors collectively determine the magnitude of the induced emf in a DC machine.

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.
How does hyrdro electric generate electricity?
hydro electric means electricity is produced by the using the Water(hydro). The water is made to fall forcely on the Turbine wheel it makes the turbine to rotate. Turbine is coupled to the Generator shaft. when the turbine rotates the generator rotates and emf is induced in it and the ourput is taken from it
When coil turns are increased the?
Induced voltage is increased

Write any two factors on which strength of induced current depends?
The strength of induced current depends on the number of coils of the cunductor and the strength of the magnet.
What determinesthe amount of current produced in the armature of a generator?
The amount of current produced in the armature of a generator is primarily determined by the voltage induced in the armature winding, the resistance of the circuit, and the load connected to the generator. According to Ohm's Law, current (I) is equal to voltage (V) divided by resistance (R) (I = V/R). Additionally, factors such as the speed of rotation of the generator, the strength of the magnetic field, and the number of turns in the coil also influence the induced voltage and, consequently, the current generated.
