Particle detectors and Flemming LH rule

In summary, a particle detector is a device used in particle physics research to identify and measure subatomic particles. It works by detecting particles through their interactions with matter, using methods such as ionization, scintillation, and Cherenkov radiation. The Flemming LH rule is a mnemonic device used to determine the direction of a magnetic field. Some common types of particle detectors include Geiger counters, scintillation detectors, calorimeters, and cloud chambers. These detectors have various applications in scientific research, medical imaging, and environmental monitoring.

(the most important aspect is the CHARGE)

Homework Equations




The Attempt at a Solution


so we know that the first finger (using flemming LHR) is into the page
but there are two possibilities:
(a) current up and force left
OR
(b) current right and force up

WHICH one would I use and why?
I have never really been able to distinguish the two from each other with regards to LH rule in questions like this

thanks

who agrees?
 

Related to Particle detectors and Flemming LH rule

1. What is a particle detector?

A particle detector is a device used to identify and measure subatomic particles, such as electrons, protons, and neutrons. These detectors are essential tools in particle physics research, as they help scientists understand the fundamental building blocks of matter.

2. How do particle detectors work?

Particle detectors work by detecting the presence and properties of particles through their interactions with matter. This can include measuring the energy, charge, and direction of particles as they pass through the detector. Different types of detectors use different methods, such as ionization, scintillation, or Cherenkov radiation, to detect and measure particles.

3. What is the Flemming LH rule?

The Flemming LH rule, also known as the right-hand rule, is a mnemonic device used to determine the direction of a magnetic field in relation to the direction of current flow. It states that if you point your thumb in the direction of current flow and curl your fingers, the direction your fingers point to is the direction of the magnetic field.

4. What are some common types of particle detectors?

Some common types of particle detectors include Geiger counters, scintillation detectors, calorimeters, and cloud chambers. Geiger counters use gas-filled tubes to detect ionizing radiation, while scintillation detectors use materials that emit light when struck by particles. Calorimeters measure the energy of particles by absorbing them, and cloud chambers use supersaturated vapor to create visible tracks of particles.

5. What are particle detectors used for?

Particle detectors have a wide range of scientific and practical applications. In particle physics, they are used to study the properties of subatomic particles and to help understand the fundamental laws of nature. They are also used in medical imaging, such as PET scans, and in environmental monitoring, such as detecting radiation levels in the environment.
