Understanding Magnetic Fields: A Comprehensive Tutorial
The Earth''s magnetic field, for example, has a strength of about 0.00005 teslas at the equator. To visualize this, imagine a bar magnet with two poles - a north pole and a south pole. The magnetic field lines extend from the north pole to the south pole, creating a circular pattern around the magnet.
Effect of magnetic field on the lithium-ion battery performance
When different magnetic field effects were loaded, the charge and discharge capacities of the lithium-ion batteries changed and increased with the enhancement of the magnetic induction intensity. In the discharge process, the greater the magnetic induction intensity, the smaller the batteries'' ohmic internal resistance and polarization internal resistance.
