Electromagnetic induction question

In summary, the conversation discusses the concept of electromagnetic induction and how a current passing through a wire can produce a magnetic field. The topic of amplifying this magnetic field through a coil and the resulting motion when placed in a magnetic field is also mentioned. The question is then raised about whether a magnetic field is produced around the coil as current flows through it during electromagnetic induction. The post also includes a clarification and a follow-up question about the relationship between induced current and magnetic fields.

Hello

I am new to this forum and wanted to ask a question on em induction.

I know if a current passes through a wire a magnetic field around the wire is produced and can be amplified by having a coil of wire. If that is then placed in a magnetic field (like between a north and south pole magnetic) motion will be produced.

With induction if a wire/coil experiences a change in magnetic field by movement of either magnet or wire, then a voltage/P.D will be produced and maybe current if it is connected to a load.

What I want to know is if current does flow through the coil during em induction when a voltage is being produced by the coil/wire will there be a magnetic field produced around the coil/wire itself as current is flowing through it?

Thank you for reading and any replies.

Can you add some punctuation marks? It is hard to read your post.

If a current flows through a coil, it produces a magnetic field, even if there are other external magnetic fields or anything else.

Sorry my question is confusing.

If current flows through a coil, (like from a battery) then is produces a magnetic field.
So if I move a coil in a magnetic field, to create a current flow through the coil will it also turn into a magnetic?

The induced current will produce a magnetic field, right.

FAQ: Electromagnetic induction question

1. What is electromagnetic induction?

Electromagnetic induction is the process of creating an electric current in a conductor by changing the magnetic field around it. This can be done by either moving a conductor through a magnetic field or changing the magnetic field itself.

2. How does electromagnetic induction work?

Electromagnetic induction works by Faraday's law, which states that a changing magnetic field induces an electromotive force (EMF) in a conductor. This EMF causes a flow of electrons, creating an electric current.

3. What applications use electromagnetic induction?

Electromagnetic induction has many practical applications, such as generators, transformers, motors, and wireless charging. It is also used in technologies such as induction cooktops and metal detectors.

4. What is the difference between electromagnetic induction and electromagnetism?

Electromagnetic induction is the process of creating an electric current by changing the magnetic field, while electromagnetism is the study of the relationship between electricity and magnetism. Electromagnetism encompasses electromagnetic induction, as well as other phenomena such as static electricity and magnetic fields.

5. How does electromagnetic induction relate to the concept of energy?

Electromagnetic induction is closely related to the concept of energy because it demonstrates the conversion of energy from one form to another. In this case, the energy from the changing magnetic field is converted into electrical energy. This principle is also seen in generators and motors, where mechanical energy is converted into electrical energy and vice versa.
