When magnetic flux changes, an electromotive force (emf) is induced in a conductor or coil according to Faraday's Law of electromagnetic induction. This induced emf can cause current to flow in a closed circuit. This phenomenon forms the basis of how generators produce electricity and how Transformers work in electrical systems.

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.
What is the formula for magnetic flux and how is it calculated?
The formula for magnetic flux is B A cos(), where is the magnetic flux, B is the magnetic field strength, A is the area of the surface, and is the angle between the magnetic field and the surface normal. Magnetic flux is calculated by multiplying the magnetic field strength, the area of the surface, and the cosine of the angle between the magnetic field and the surface normal.
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 flux that does not follow the intended path in a magnetic circuit?
Leakage flux is the flux that does not follow the intended path in a magnetic circuit. It represents the magnetic field that strays outside of the core and does not contribute to the desired magnetic coupling between the components of the circuit. Strategies such as improving the design and materials of the magnetic circuit can help minimize leakage flux.
What happens to the sideways force when flux density increases?
When flux density increases, the force experienced by a current-carrying conductor due to a magnetic field (sideways force in this case) will also increase. This is because the force is directly proportional to the magnetic flux density and the current in the conductor.
Unit of Magnetic flux?
A unit of magnetic flux is called a Weber.

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.
Is flux only produce in ac supply or in both ac and dc?
Flux is produced in both AC and DC systems, but the nature of the flux differs. In DC circuits, the magnetic flux is constant, as the current flows in one direction. In AC circuits, the magnetic flux changes direction and magnitude periodically, resulting in a time-varying magnetic field. Thus, while both types of current can produce flux, AC generates a dynamic flux due to its oscillating nature.
Which process converts binary information into patterns of magnetic flux on a hard disks surface?
The process that converts binary information into patterns of magnetic flux on a hard disk's surface is called magnetic recording. This involves encoding binary data (0s and 1s) into magnetic fields, which are created by the read/write head of the hard drive. The head alters the magnetic orientation of tiny regions on the disk's surface, representing the stored data as changes in magnetic flux. When data is read, the changes in magnetic orientation are detected and translated back into binary information.
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.
What is the formula for magnetic flux and how is it calculated?
The formula for magnetic flux is B A cos(), where is the magnetic flux, B is the magnetic field strength, A is the area of the surface, and is the angle between the magnetic field and the surface normal. Magnetic flux is calculated by multiplying the magnetic field strength, the area of the surface, and the cosine of the angle between the magnetic field and the surface normal.
What is Magnetic flux density unit?
"Magnetic flux density" is also known as the magnetic field,The SI unit for this is the Tesla, written as T.CommentMagnetic flux density is not "also known as the magnetic field". It describes the intensity of a magnetic field.
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.

Why reluctance is dependet on magnetic flux?
It isn't. However, the ratio of magnetomotive force to magnetic flux will tell you what the reluctance happens to be for that particular ratio, in exactly the same way that resistance isn't dependent on current, but the ratio of voltage to current will tell us what the resistance happens to be for that particular ratio.
