QuestionAnswer
A current generated in a conductor due to the presence of a changing magnetic field, according to Faraday's law of electromagnetic induction.Induced Current
What is the primary cause of an induced current in a conductor?An induced current arises in a conductor when it experiences a changing magnetic field, as per Faraday's law of electromagnetic induction.
The region surrounding a magnet or current-carrying conductor where magnetic forces are exerted on other magnets or conductors.Magnetic Field
How does an induced current contribute to the generation of a magnetic field?An induced current in a conductor produces its own magnetic field, creating a magnetic force in the surrounding space.
A voltage or electrical potential difference induced in a conductor due to the relative motion between a magnet and the conductor, leading to the generation of an induced current.Induced Potential Difference
What conditions are necessary for the generation of an induced potential difference in a conductor?An induced potential difference is created by the relative movement of a magnet and a conductor, according to the principles of electromagnetic induction.
A fundamental principle stating that a changing magnetic field induces an electromotive force (EMF) or voltage in a nearby conductor, leading to the generation of an induced current.Faraday's Law of Electromagnetic Induction
How does Faraday's law explain the phenomenon of electromagnetic induction?Faraday's law elucidates that a changing magnetic field induces an electromotive force in a conductor, resulting in the generation of an induced current.
The voltage or electrical potential difference induced in a conductor due to the presence of a changing magnetic field, leading to the generation of an induced current.Electromotive Force (EMF)
What role does the induced magnetic field play in relation to the original change that created it?The induced magnetic field opposes the original change that produced it, exemplified by the repulsion of a magnet from a coil when the magnet is moved into the coil, as per Lenz's law.
The voltage or electrical potential difference induced in a conductor due to the presence of a changing magnetic field, according to Faraday's law of electromagnetic induction.Induced Potential Difference
What are the three factors that can affect the size of the induced potential difference?The size of the induced potential difference can be increased by increasing the speed of movement between the conductor and magnetic field, using a stronger magnetic field and adding more turns to the wire coil.
Faraday's law states that the magnitude of the induced potential difference is proportional to the rate of change of magnetic flux through the conductor.Faraday's Law in Relation to Induced Potential Difference
How does increasing the speed of movement affect the induced potential difference?Increasing the speed of movement between the conductor and the magnetic field results in a larger induced potential difference, as per Faraday's law.
The measure of the quantity of magnetic field lines passing through a surface perpendicular to the field.Magnetic Flux
What role does magnetic flux play in the generation of an induced potential difference?According to Faraday's law, the induced potential difference is proportional to the rate of change of magnetic flux through the conductor.
The speed at which magnetic flux through a conductor changes, influencing the magnitude of the induced potential difference.Rate of Change of Magnetic Flux
How does a stronger magnetic field affect the induced potential difference?Using a stronger magnetic field increases the induced potential difference, in accordance with Faraday's law, as it enhances the rate of change of magnetic flux.
A coil of wire commonly used in electromagnetic devices, such as generators and transformers.Wire Coil
How does adding more turns to the wire coil impact the induced potential difference?Adding more turns to the wire coil increases the induced potential difference, as it multiplies the effect of the changing magnetic flux, as per Faraday's law.
