Relativistic cyclotron frequency

In summary, the conversation discusses whether the transverse mass should be considered in the formula for centripetal force and how to express the force in terms of momentum. It is suggested that the transverse mass should be included and the equation for momentum is pv/r=qvB.

Since the acceleration is transverse to the velocity, should we consider the transverse mass in the formula [itex]mv^2/r[/itex] ie

[itex]\gamma \frac{mv^2}{r} = qvB \implies \frac{v}{\sqrt{1-(v/c)^2}} = \frac{qBr}{m} [/itex]?

How can you express the centripetal force in terms of momentum (with other terms)?
How is the relativistic momentum?

Yes. But just to be clear, using your symbols, the transverse mass = gamma*m.

It's clearer in terms of momentum pv/r=qvB-->p=qBr.
 

Related to Relativistic cyclotron frequency

What is the relativistic cyclotron frequency?

The relativistic cyclotron frequency is the frequency at which a charged particle, such as an electron, moves in a circular or helical path under the influence of a magnetic field. It takes into account the relativistic effects of the particle's mass and velocity.

How is the relativistic cyclotron frequency calculated?

The relativistic cyclotron frequency is calculated using the formula f = qB/2πγm, where q is the charge of the particle, B is the strength of the magnetic field, γ is the Lorentz factor, and m is the mass of the particle.

What is the significance of the relativistic cyclotron frequency?

The relativistic cyclotron frequency is significant because it is used to study the behavior of charged particles in magnetic fields, which is important in many areas of physics, including particle accelerators, plasma physics, and astrophysics.

How does the relativistic cyclotron frequency differ from the classical cyclotron frequency?

The relativistic cyclotron frequency takes into account the relativistic effects of the particle's mass and velocity, whereas the classical cyclotron frequency only considers the mass of the particle. This means that the relativistic cyclotron frequency will be higher than the classical cyclotron frequency for particles with high speeds or large masses.

Can the relativistic cyclotron frequency be observed in real-life situations?

Yes, the relativistic cyclotron frequency can be observed in many real-life situations, such as in particle accelerators, where charged particles are accelerated to high speeds and then bent by magnetic fields to create circular paths. It is also observed in natural phenomena, such as the motion of charged particles in Earth's magnetic field.
