# Induced emf with no change in flux

• girlzrule786
In summary, when a loop is moved perpendicularly in a uniform magnetic field, there is no change in flux and therefore no induced emf according to Faraday's law. The deflection force mentioned may be referring to the Lorentz force, but it is not clear if this would result in an induced emf.

If a loop is moved in a uniform magnetic field such that the direction of its motion is perpendicular to the magnetic field, then no change of flux occurs. Then according to faraday, no emf is induced...

But I was thinking that can the emf be produced in it due to the deflection force?

Hi girlzrule786!

What is the "deflection force"?
I tried to look it up, but the first hit said it was a special power of the Jedi in Star Wars.
Somehow I don't think that is what you meant!

Did you perhaps mean the Lorentz force?

## 1. What is induced emf with no change in flux?

Induced emf with no change in flux refers to the phenomenon where an electromotive force (emf) is produced in a circuit without any change in the magnetic flux through the circuit. This can occur when a conductor moves through a uniform magnetic field at a constant velocity or when the magnetic field itself is varied at a constant rate.

## 2. How is induced emf with no change in flux different from regular induced emf?

In regular induced emf, there is a change in the magnetic flux through the circuit, which leads to the production of an emf. However, in induced emf with no change in flux, there is no change in the magnetic flux, but an emf is still produced due to the movement of a conductor or a varying magnetic field.

## 3. What is the significance of induced emf with no change in flux?

Induced emf with no change in flux is an important concept in electromagnetism and has various practical applications. It is used in devices such as generators, transformers, and induction motors. It also helps in understanding the principles of electromagnetic induction and the relationship between electricity and magnetism.

## 4. What factors affect induced emf with no change in flux?

The magnitude of induced emf with no change in flux depends on several factors, including the strength of the magnetic field, the velocity of the conductor, the length of the conductor, and the angle between the magnetic field and the conductor. Additionally, the number of turns in the circuit and the resistance of the circuit also play a role.

## 5. How is Lenz's law related to induced emf with no change in flux?

Lenz's law states that the direction of the induced emf in a circuit is such that it opposes the change in magnetic flux that caused it. In the case of induced emf with no change in flux, Lenz's law still applies, and the direction of the induced emf will be opposite to the direction of the movement of the conductor or the change in the magnetic field.
