What is the flux linkage formula used to calculate the total magnetic flux passing through a coil of wire?
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.
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 do you calculate the pole strength of a magnetic?
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.
How can the magnetic flux associated with coil or a closed circuit be changed?
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.
Unit of Magnetic flux?
A unit of magnetic flux is called a Weber.
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.

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.
What is the eddy current formula used to calculate the induced currents generated by changing magnetic fields in a conductor?
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.
What is the effect of variable area to the magnetic flux within the solenoid at constant number of windings and current?
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.
What is the direction of magnetic flux in a magnetic field?
The direction of magnetic flux in a magnetic field is from the north pole to the south pole.
How is an electormotive force induced in a coil?
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.
