Magnetic Field -- break in the continuity of a conductor

In summary, the conversation discusses the effects of a break in the continuity of a conductor's volume on its magnetic field and resistance. It is stated that a continuous circuit is necessary for an electric current to generate a magnetic field, and resistance is proportional to the effective area of the conductor. The possibility of detecting microscopic fractures in a conductor is also mentioned, with reflectometry being one possible method. The speaker also asks about the effectiveness of reflectometry for low-frequency radiation.

Hi! Just curious...
Does a break in the continuity of a conductor's volume affect its magnetic field, resistance, etc?

A continuous circuit is necessary for an electric current and an electric current of charges is required to generate a magnetic field. Now if you mean a nick in the volume, then resistance is proportional to the effective area of the conductor.

thanks for the reply.
what if the cross-sectional area of a conductor is not uniform, say there are microscopic fractures in a certain region, is there some way to detect this?
Does this make sense?

Sure, makes sense, and yes, many ways. Reflectometry from my experience, or merely resistance of the conductor.

this is just amazing! does reflectometry work even for low-frequency radiation? I only know xray reflectometry.
 

1. What is a magnetic field break in the continuity of a conductor?

A magnetic field break in the continuity of a conductor is when there is a physical gap or interruption in the path of the conductor, causing a disruption in the flow of the magnetic field.

2. What causes a break in the continuity of a conductor?

A break in the continuity of a conductor can be caused by physical damage, such as a cut or break in the wire, or by electromagnetic interference.

3. How does a break in the continuity of a conductor affect the magnetic field?

A break in the continuity of a conductor can cause the magnetic field to weaken or even collapse in the area of the break. This can also cause changes in the direction or strength of the magnetic field.

4. Can a break in the continuity of a conductor be repaired?

In most cases, a break in the continuity of a conductor can be repaired by physically reconnecting the two ends of the conductor. However, in some cases, the damage may be extensive and the conductor may need to be replaced.

5. How can a break in the continuity of a conductor be prevented?

To prevent a break in the continuity of a conductor, proper insulation and protection should be used to prevent physical damage. In addition, proper grounding and shielding can help prevent electromagnetic interference that could cause a break in the continuity.
