Why should the flux density increase with the speed of the magnets?
It is because induction of electricity depends on rate of change of flux and it means the speed of magnet
Does constant magnetic flux in a coil induce a current in it?
Faraday's Law: the E.M.F. induced in a conductor [the current is caused by the E.M.F.] is directly propotional to the rate of change of magnetic flux linkage.A constant magnetic flux isn't changing, so the rate of change is zero and the induced E.M.F is zero. No E.M.F. = no current.
What is Faraday's 1st law?
Faradays first law state that the rate of change of Magnetic flux is directly proportional to emf induced
What is the effect of variable area to the magnetic flux within the solenoid at constant number of windings and current?
area is equal to the magnetic flux, therefore it is equal.
How is acceleration similar to speed and velocity?
-- The magnitude of acceleration is equal to the time rate of change of speed. -- The magnitude of acceleration is equal to the time rate of change of the magnitude of velocity. -- Acceleration and velocity are both vectors.
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.
Why is rate of change of flux linking primary and secondary coils the same?
The 'rate of change' applies to the flux itself, and has nothing to do with it linking the primary and secondary windings. There is only one flux, so of course the rate of change is 'the same'.

What is Faraday second law of electromagnetic induction?
Second Law of Faraday's Electromagnetic Induction state that the induced emf is equal to the rate of change of flux linkages (flux linkages is the product of turns, n of the coil and the flux associated with it).
How does a dc generator function?
The working principle is Faraday's law of electromagnetic induction. "Whenever a conductor experience the rate of change of magnetic flux an e.m.f. is induced in it",which is directly proportional to the rate of change of magnetic flux and no of conductors.
How Michael Faraday discovered electromagnetic induction?
Move a magnet into a coil, and a voltage is induced into that coil, causing a galvanometer to deflect. Withdraw the magnet, and the galvanometer will deflect in the opposite direction, indicating that the induced voltage depends upon the direction of motion of the magnet.
Why should the flux density increase with the speed of the magnets?
It is because induction of electricity depends on rate of change of flux and it means the speed of magnet

Which law states that voltage is induced in a circuit whenever the flux linking the circuit is changing and that the magnitude of the voltage is proportional to the rate of change of the flux linkage?
Faraday's Law.
How can the maglev train be made to go faster and slower?
The speed is controlled by the rate of change in the magnetic flux in the road-bed.
What does a Mega Flux do in AQW?
A Mega Flux is equal to 5 normal fluxes.
What is the conversion rate for euros to dollars?
The conversion rate for these two currencies is in a state of constant flux. Currently, 1 euro equals 1.31 U.S. dollars. This rate, however, is subject to change.
