In high school physics, we know that a charged particle cannot gain energy from a magnetic field. But, it seems that in the so-called Fermi accelerationFermi acceleration, the particle is accelerated by the magnetic field. How does it happen?

Is it because the magnetic field is not stationary?

A question about the Fermi acceleration

In high school physics, we know that a charged particle cannot gain energy from a magnetic field. But, it seems that in the so-called Fermi acceleration, the particle is accelerated by the magnetic field. How does it happen?

Is it because the magnetic field is not stationary?
