Continuing entanglement after first measurement

    Ok so if two particles are entangled and I choose to measure particle A, then the entanglement is finished. But what if I measure both A and B with photons of the exact same energy; is there now a new entanglement?

    Additionally, if the spn is changed, can the entanglement continue? Placing a particle into an electric field to separate the spin state energy levels (this is called something called the Zeeman effect and was one of the reasons we made the mistake of calling the property spin in the first place) and then putting in sufficient energy (usually radio waves) will change the spin state of that particle. This is the basis for NMR and MRI.
