# Magnetic & Electric Fields: A Cycle of Change?

• MotoPayton
In summary, magnetic fields are areas around a magnet or a moving electric charge where the magnetic force acts, while electric fields are areas around electrically charged particles where the electric force acts. These fields can interact with each other, create forces, and generate electromagnetic waves. They can also change in strength and direction over time, resulting in the electromagnetic cycle. These fields have practical applications in technology and can affect living organisms both positively and negatively.

A changing magnetic field creates a non conservative electric field. If the changing magnetic field is accelerating(2nd derivative in non-zero) the electric field must also be changing. Would this mean that the changing electric field is producing a magnetic field.

Depending on the order of derivative this could continue indefinitely.

B=e^t for example...

Sure, that's the way that electromagnetic waves work!

## 1. What are magnetic and electric fields?

Magnetic fields are areas around a magnet or a moving electric charge where the magnetic force acts. Electric fields are areas around electrically charged particles where the electric force acts. Both fields are fundamental to the behavior of electricity and magnetism.

## 2. How do magnetic and electric fields interact?

Magnetic and electric fields can interact in a variety of ways. Electric fields can create magnetic fields and vice versa. They can also exert forces on each other, causing particles to move and generating electromagnetic waves.

## 3. How do magnetic and electric fields change over time?

Magnetic and electric fields can change in strength and direction over time due to the movement of electric charges or magnets. This results in a cyclical pattern of change, known as the electromagnetic cycle.

## 4. What are the practical applications of magnetic and electric fields?

Magnetic and electric fields have numerous practical applications, including generators, motors, transformers, and MRI machines. They are also crucial in modern technology, such as computers, televisions, and cell phones.

## 5. How do magnetic and electric fields affect living organisms?

Magnetic and electric fields can have both positive and negative effects on living organisms. For example, they play a crucial role in the navigation system of some animals, but can also have harmful effects on the body's cells if exposed to high levels for extended periods of time.
