👉 In quantum mechanics, a fermion is an entity that interacts with the electromagnetic field in a way similar to bosons, but it can also interact with other particles. In this context, a fermion refers to a particle that has integer spin and is composed of two Majorana fermions (the "bosonic" part) and one Majorana spinor (the "fermionic" part). These particles are known as fermions in the context of quantum mechanics because they interact with electromagnet
