WebThe magnetic properties of a matter can be concluded by testing the arrangement of its electrons. When at least one electron is irregular in their orbit then the matter is paramagnetic in nature. Whereas when two electrons are attached together then the matter is called to be diamagnetic. Web11 jun. 2024 · These vaccines contain no paramagnetic material, and even if they did, there would not be enough in the tiny amount of material injected to create a detectable magnetic field. We already have a significant amount of iron in our body, roughly 3.5 grams, and we don’t feel any attraction when we encounter even an extremely powerful magnet.
