Why will there be no induced current?

Therefore, there will not be an induced current in a field parallel to a current carrying wire. In summary, current cannot be induced in a field unless there is a conductor or ionized gas present. Additionally, if there is no changing field, no voltage is being induced and therefore no current can be induced.

Will you please post the reference, textbook, paper, or whatever that is the source of your question?

Current cannot be induced in a field. Current needs some conductor like copper or ionized gas in order to flow.

Here on Physics Forums we are not supposed to bump our posts.

those pics are not referring to current induced into a field


and as bobby said ... it cannot be, so what really is your question ?

If no field lines cross (i.e., cut through) the enclosed area, there is no changing field. If there is no changing field, no voltage is being induced.
 

1. Why is there no induced current in a stationary loop?

Induced current is generated when there is a change in magnetic field, such as when a magnet moves relative to a stationary loop. However, in a stationary loop, there is no changing magnetic field and therefore no induced current.

2. What is the difference between induced current and direct current?

Induced current is generated by a changing magnetic field, while direct current is a continuous flow of electrons in a circuit. Induced current only lasts as long as the changing magnetic field is present, while direct current can be sustained indefinitely.

3. Can induced current be controlled?

Yes, the strength and direction of induced current can be controlled by changing the strength and direction of the magnetic field or by changing the orientation of the loop relative to the magnetic field.

4. How is induced current used in everyday life?

Induced current is used in many devices, such as generators, transformers, and electric motors. It is also used in wireless charging technology and electromagnetic induction cooktops.

5. What is Faraday's law and how does it relate to induced current?

Faraday's law states that a changing magnetic field will induce an electromotive force (EMF) in a conductor, which can then create a current. This is the basis for understanding and explaining the phenomenon of induced current.
