WebAs I know, in magnetic objects there are many magnetic dipoles, which in turn is a loop current. So, basically, the magnetic field created by the first object will act a force (Lorentz force) on loop currents of the second object. It's similar to the force 2 parallel currents act on each other.

Web0. According to this page: The iron cores used in conventional electromagnets saturate and cease to provide any advantage at fields above a few teslas, so iron core electromagnets are limited to fields of about 2 teslas. Superconducting electromagnets can produce stronger magnetic fields but are limited to fields of 10 to 20 teslas, due to flux ... Web8 de set. de 2024 · Magnetism can be described as a force that attracts and repels magnetic objects. This force is mediated by magnetic fields that penetrate different media. Some materials naturally have magnetism as a default property. However, certain materials can be magnetised or demagnetised according to the requirements.
