Photon o係magnetic field有冇deflection in QED

如果用Quantum Electrodynamics 黎諗, photon係electromagnetism interactive particle. 如果我放兩塊強力磁石, 放個strong gamma source,

o甘會唔會"無中生有", 出正反particles, 定係都仲係superposition?

我想請問一下
你想用chem 定phy 既角度來睇依個問題呢?
仲有既係
你係AL level?

No, I don't think there is a deflection of photons in a magnetic field. The classical electromagnetic theory can also deduce this, without using QED (I believe ...).

Instead, something very weird may occur if a photon is subjected to a very strong magnetic field. Photon splitting yielding such as neutrino-antineutrino pair may occur according to QED.

For your interest, you can read the following literature
Nature, Volume 202, p.684-685
