If a time varying magnetic field exists in vertically downwards direction in a region A, an electric field is induced in the direction perpendicular to it i.e. in horizontal plane. How to find the direction of the E field in the horizontal plane?What factors decide the direction of the E field?

Once in a book I read that the E field lines form closed loops. If that is true practically then what factors decide the center of the closed loop? Or is the E field induced is just randomly directed?

Do you know Faraday's law? It says that ##\int{\vec{E}.d\vec{l}}## = -##\frac{∂Φ}{∂t}## where Φ is the magnetic flux. So the direction of the induced electric field is dependent on the sign of the change in magnetic flux.

## 1. What is the direction of the induced electric field?

The direction of the induced electric field is always perpendicular to the direction of the changing magnetic field. This is known as Faraday's law of induction.

## 2. How is the direction of the induced electric field determined?

The direction of the induced electric field is determined by Lenz's law, which states that the induced electric field will always oppose the change in the magnetic field that caused it.

## 3. Can the direction of the induced electric field change?

Yes, the direction of the induced electric field can change if the direction of the changing magnetic field changes. This is because the induced electric field will always try to oppose the change in the magnetic field.

## 4. What factors affect the direction of the induced electric field?

The direction of the induced electric field is affected by the strength and direction of the changing magnetic field, as well as the material properties of the conductor through which the magnetic field is passing.

## 5. How does the direction of the induced electric field relate to electromagnetic induction?

The direction of the induced electric field is a result of electromagnetic induction, which is the production of an electric current in a conductor due to the presence of a changing magnetic field. The direction of the induced electric field is dependent on the changing magnetic field and the properties of the conductor.
