IB Physics: Activity: NMR imaging

When a proton is placed in a strong magnetic field it can have two possible energy states. It is as if they are small magnets that can either be aligned with the field or against it. In the image below the B field is directed upwards.We can see that the magnets either point up or down, down is a higher energy state than up.WORKWhen a magnet changes from down to up energy is released.
