Magnetic field effect could affect the lithium-ion batteries performance. The magnetic field magnetize the battery, and many small magnetic dipoles appear, so that the particles in the battery have magnetic arrangement, and then the ionic conductivity is improved, and the flow and diffusion of ions are accelerated.
They have revisited a model for the generation of small magnetic fields in a plasma, called the Biermann battery, and shown that this process could have generated seed fields in the Universe much earlier than was previously thought possible. Although the fields they calculate are weak, the fact that they could have existed early in the age of the Universe

Test out the magnet while holding the wire onto ends of the battery. Once you have a good grip on the battery with the wires, test it out! Hold the battery and iron close to a small metal object, such as a
When the wire touches the top of the battery and the magnet (which is touching the bottom of the battery) at the same time, electrical current flows through the wire. This electrical current passes through the magnetic field created by the magnet. This results in a force that pushes on the wire, causing it to spin around the battery. This spinning motion means it is a simple electric motor, a

What Is Induction? We have seen how Ørsted was able to demonstrate that electric currents can produce magnetic fields. The English physicist Michael Faraday, a brilliant experimentalist, was the first to demonstrate the converse effect just a few years later in 1831: magnetic fields can be used to induce electric currents.This is now called the principle of magnetic induction.

Magnetic field lines are the lines in a magnetic field the tangent of which at any point will give the field direction at that point and its density gives the magnitude of the field. The magnetic field intensity depends on the number of magnetic field lines. The lines are higher at the poles, that is why the magnetic field at the poles is stronger.

The magnetic field around each battery with the solenoid off was measured to be less than 20 pT in any direction before performing experiments. This field (due to remnant magnetization) was mapped for each cell with the solenoid field off and subtracted from the induced field maps.
