# Best answer: Which describes that changing electric fields generate magnetic fields?

Contents

Faraday’s law describes how changing magnetic fields produce electric fields. The displacement current introduced by Maxwell results instead from a changing electric field and accounts for a changing electric field producing a magnetic field.

## How does changing electric field produce magnetic field?

– Note that the electric and magnetic fields are perpendicular to each other. … Since a changing magnetic field creates an electric field and a changing electric field creates a magnetic field, these two oscillating fields continue to reinforce each other, and the wave propagates through space.

## What does changing electric field induce?

What does a changing electric field induce? A changing magnetic field. “If light were to speed up, the changing electric field would generate a stronger magnetic field, which in turn would generate a stronger electric field, etc.” … An oscillating or accelerating electric charge.

## Does changing magnetic field produce magnetic field?

Faraday’s Law of Induction describes how an electric current produces a magnetic field and, conversely, how a changing magnetic field generates an electric current in a conductor.

## Does changing magnetic field produce an electric field and a changing electric field produces a magnetic field?

Then they cannot be treated independently of each other, because the changing electric field produces a changing magnetic field and the newly produced changing magnetic field produces a changing electric field, which is an electromagnetic wave.

NEED TO KNOW:  How do you calculate nuclear binding energy per nucleon?

## What is an example of an electromagnetic field?

Electromagnetic fields are a combination of invisible electric and magnetic fields of force. … Mobile phones, power lines and computer screens are examples of equipment that generates electromagnetic fields.

## Which is stronger magnetic field or electric field?

An electromagnetic field (also EM field) is a classical (i.e. non-quantum) field produced by accelerating electric charges. … The force created by the electric field is much stronger than the force created by the magnetic field.

## How is emf related to electric field?

EMF is a combination of electrical and magnetic fields. … That means the more current or the higher the voltage, the greater the EMF which could be generated. Electric fields are measured in volts per meter (V/m). A one volt electrical potential one meter away will have an electric field of 1 V/m.

## How do you get the induced electric field?

When the magnetic flux through a circuit changes, a nonconservative electric field is induced, which drives current through the circuit.
