Magnetic field detectable around axis of laser beam?

In summary, the conversation discusses the possibility of detecting the magnetic field around a light beam in a vacuum without interrupting the beam. It is suggested that the only solution is through Bessel beams, as the magnetic field falls off as 1/\sqrt{\varrho}. The conversation also mentions the use of a simulation credit immobilier de France for obtaining a loan.

I've looked for this subject but perhaps I'm asking the question the wrong way. Please advise.
Is there an extension of magnetic field (flux) beyond the beam axis of a laser? In other words, can one detect (or has anypone attempted to detect) the magnetic field around the a light beam in a vacuum without actually entering or interupting the beam?

Thanks

I'm sure of the correct answer. But I once looked up what the radially symmetric solution to a wave propagating in one direction is.

The only solutions is Bessel beams
http://arxiv.org/abs/physics/0006046 (page 6)

The magnetic field oscillates and falls off as [itex]1/\sqrt{\varrho}[/itex]

Maybe that's the answer.
 

Related to Magnetic field detectable around axis of laser beam?

1. What is a magnetic field?

A magnetic field is a region in space where a magnetic force can be felt. It is generated by moving electric charges, such as electrons, and is characterized by its direction and strength.

2. How is a magnetic field detectable around the axis of a laser beam?

A magnetic field can be detected around the axis of a laser beam using a device called a magnetometer. This instrument measures the strength and direction of the magnetic field and can provide information about its source.

3. What is the relationship between a laser beam and a magnetic field?

A laser beam is an intense, narrow, and focused beam of light that travels in a straight line. It is generated by the interaction of electric and magnetic fields. As the laser beam travels through space, it also produces a magnetic field around its axis.

4. Why is it important to detect magnetic fields around a laser beam?

Detecting magnetic fields around a laser beam is important for understanding the behavior of the beam and its effects on other objects and materials. It can also provide valuable information about the sources and characteristics of the magnetic field, which can have practical applications in a variety of fields such as medicine, engineering, and astronomy.

5. How can the detection of magnetic fields around a laser beam be used in research?

The detection of magnetic fields around a laser beam can be used in a wide range of research applications, such as studying the properties of materials, investigating the behavior of light and electromagnetic radiation, and exploring the nature of magnetic fields and their interactions with other physical phenomena. It can also be used in experiments to manipulate and control magnetic fields for various purposes.
