Aluminum coil itself does not have a direct relationship with magnetic fields in terms of magnetic properties, as aluminum is not a magnetic material and does not get magnetized. However, when an aluminum coil is part of an electrical circuit, it can interact with magnetic fields in the context of electromagnetic induction. If a changing magnetic field passes through an aluminum coil, it can induce an electromotive force (EMF) or voltage in the coil, according to Faraday's law of electromagnetic induction. This induced voltage can cause an electric current to flow through the coil if it is part of a closed circuit. The aluminum coil's primary interaction with magnetic fields is thus through the generation of electrical current when used in conjunction with an electric circuit.
