Does the shape of a conductor affect the induced magnetic field?

In summary, when a conductor moves through a steady-state magnetic field, the induced field is proportional to the field and can be represented by a 3-by-3 constant matrix. However, this is only a first-order approximation and the actual induced field depends on the magnetic field and velocity of the conductor at all points. This problem can be further explored in various texts and references.

If an arbitrary shaped conductor is moving through a steady-state magnetic field, [itex]\mathbf{B}(\mathbf{r})[/itex], is it true that the field induced in the conductor will be proportional to [itex]\mathbf{B}[/itex]? IE:

[tex]
\mathbf{B}_{induced}(\mathbf{r}) = M \mathbf{B}(\mathbf{r})
[/tex]

where [itex]M[/itex] is a 3-by-3 constant matrix? Or is this simply a first-order approximation to the induced field? Does anyone know of any texts or references which treat this problem? Thanks.

As you consider an induced magnetic field, I guess your conductor is a closed loop (or at least has some circular current paths)?

You cannot evaluate the field point by point. The induced field at one point will depend on the magnetic field everywhere else (and the velocity of the conductor everywhere).
 

FAQ: Does the shape of a conductor affect the induced magnetic field?

What is a field induced in a conductor?

A field induced in a conductor refers to the creation of an electric field inside a conductor when an external electric field is applied. This phenomenon is also known as induced polarization.

How is a field induced in a conductor?

A field is induced in a conductor when an external electric field is applied, causing the charges within the conductor to redistribute. This redistribution of charges creates a new electric field that opposes the external field.

What is the significance of a field induced in a conductor?

The presence of a field induced in a conductor can affect the behavior and properties of the conductor. For example, it can affect the flow of current, the capacitance, and the resistance of the conductor.

Can a conductor have multiple fields induced in it?

Yes, a conductor can have multiple fields induced in it. This can occur when multiple external electric fields are applied, or when the conductor is in close proximity to other conductors or charged objects.

How does the presence of a magnetic field affect a field induced in a conductor?

The presence of a magnetic field can affect the strength and direction of a field induced in a conductor. This is known as the Hall effect, where the induced field is perpendicular to both the external electric field and the magnetic field.
