How do i calculate the delta of the Spell check your answer equation,emf=-N(delta.BA/delta.t)
always subtract larger value from smaller one if both initial and final flux is given,secondly you can use phi=B.Acos theta (ref:roger muncaster A-level phy)
The flux linkage formula used to calculate the total magnetic flux passing through a coil of wire is given by the equation N, where represents the magnetic flux, N is the number of turns in the coil, and is the magnetic flux per turn.
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.
The pole strength of a magnetic can be calculated by measuring the magnetic flux that it produces and dividing it by the area of the pole face. The formula to calculate the pole strength is: Pole Strength = Magnetic Flux / Area of pole face.
A simple method for altering the magnetic flux would be to change the amount of current flowing in the coil or circuit. Generally speaking, more current, more magnetic flux, and vice versa.
A unit of magnetic flux is called a Weber.
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.

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.
The formula to calculate eddy currents in a conductor due to changing magnetic fields is given by: E -d/dt, where E represents the induced electromotive force, is the magnetic flux, and dt is the change in time.
Increasing the variable area of the solenoid will result in a change in the magnetic flux within the solenoid while keeping the number of windings and current constant. This is because the magnetic flux is directly proportional to the cross-sectional area of the solenoid. Therefore, as the area increases, the magnetic flux will also increase, and vice versa.
The direction of magnetic flux in a magnetic field is from the north pole to the south pole.
An electromotive force (emf) is induced in a coil when there is a change in magnetic flux passing through the coil. This change in magnetic flux can be caused by either moving a magnet near the coil or by changing the current flowing through a nearby coil. According to Faraday's Law of electromagnetic induction, the emf induced in the coil is proportional to the rate of change of magnetic flux.
