Magnetic Field Force on Parallel Moving Charges

In summary, the question is why moving charges or currents parallel to a magnetic field are not affected by the field. This may be due to the orientation of the field created by the moving charge in relation to the existing field. While there may not be a clear answer yet, one theory suggests that magnetic fields transfer energy to objects through variations in field strength, and since parallel movement does not cause a change in intensity, there would be no transfer of energy. This is the understanding of the conversation, but further clarification is welcome.

Why don't magnetic fields not force to charges/currents that are moving parallel to the field?

Does it have something to do with the orientation of the field created by the moving charge in relation to the field it is in?

I know the answer of this question may not be clear yet, but are there any theories?

You use a double negative in the first part of your sentence that is confusing (do not and not), but I think I understand your question.

Magnetic fields transfer energy to objects by variation of the field strength. If the sensing element (say a charged particle) moves parallel to the field it, by definition of parallel, will not experience any change in the intensity of the magnetic field. No variation, no transfer of energy.

Ok you guys out there; did I get that right?
 

Related to Magnetic Field Force on Parallel Moving Charges

1. What is the magnetic field force on parallel moving charges?

The magnetic field force on parallel moving charges is a force that is exerted on two or more charged particles that are moving in parallel paths. It is a result of the interaction between the magnetic fields created by the charges.

2. How is the magnetic field force calculated?

The magnetic field force can be calculated using the formula F = qvB, where q is the charge of the particle, v is its velocity, and B is the magnetic field strength. This formula is also known as the Lorentz force law.

3. What is the direction of the magnetic field force on parallel moving charges?

The direction of the magnetic field force is perpendicular to both the direction of the magnetic field and the direction of the particle's velocity. This means that the force will be either towards or away from the center of the circle formed by the moving charges, depending on the direction of the magnetic field.

4. How does the magnetic field affect the motion of parallel charges?

The magnetic field force can change the direction of the particles' motion, causing them to move in circular paths. The magnitude of the force also depends on the strength of the magnetic field and the velocity of the charges.

5. What are some real-life applications of the magnetic field force on parallel moving charges?

The magnetic field force on parallel moving charges is the principle behind many technologies, such as particle accelerators, mass spectrometers, and magnetic resonance imaging (MRI) machines. It is also essential for understanding the behavior of charged particles in the Earth's magnetic field and in space.
