What else can I help you with?
What does induction mean in science?
the phenomenon of generation of emf by means of change in flux.
How is a moving magnet used to create electricity?
makes current flow through a magnet
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.
How do magnets help generator produce electricity?
Magnets would have magnetic flux around. As a coil linked with this magnetic flux is rotated such that the flux would change then an electro motive force is induced. This is the way in which generator functions.
Do electrical charges cause electricity?
YES, electricity is caused by the separation of electrical charge which, through means of trying to stabilize itself (in other words become neutral) causes the flux (or motion) of electrons. The flow of electrons is what electricity really is.
What words have the latin root flux?
flux (a regular or continual change) fluctuate (to continually change)
What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.
How flux is related to speed?
Flux is related to the speed of change in a physical quantity through the concept of flux density. Flux density is the amount of flux passing through a unit area per unit time. The faster the change in the physical quantity, the higher the flux density.
Why should the flux density increase with the speed of the magnets?
As the magnets move faster, they generate a stronger magnetic field, which leads to an increase in the flux density. This is known as Faraday's law of electromagnetic induction. The rate of change of the magnetic field intensity is directly proportional to the induced electromotive force (EMF).
What are the cause of induced emf?
A change in current causes a voltage to be induced into an inductive circuit, which opposes that change of current. This is because the change in current is accompanied by a change in magnetic flux which 'cuts' the conductors and induces a voltage into them.
What change occurs in flux when load increases in DC shunt motor?
no change occurs because the flux is controlled by the supply and not the load on the generator. thus flux doesnot change unless the supply changes
How the electricity is obtained?
By cutting lines of magnetic flux through an electromagnet
