(2021) demonstrated that external magnetic fields can cause energy dissipation in certain battery types due to eddy currents. Eddy currents are loops of electric current induced within conductors by a changing magnetic field. These currents can generate heat, reducing overall efficiency.
-
Internal resistance: Magnetic fields can change internal resistance in batteries. Increased resistance can affect the rate at which a battery can deliver energy. Blanckenburg and Müller (2020) found that changes in magnetic environments can lead to increased internal resistance, leading to lower efficiency in energy transfer.
