Guide Magnetic Effect
MAGNETIC EFFECT OF CURRENT Hans Oersted, in 1820, first discovered that when an electric current is passed through a conducting wire, a magnetic field is produced around it. If a compass needle is kept in the vicinity of the current carrying wire, the needle is found to deflect in a definite direction. If the direction of current in the wire is reversed, Then the

How does a magnetic field affect a battery?
In summary, the magnetic field can non-destructively monitor the status of batteries such as the current distribution, health, changes in temperature, material purity, conductivity, phase changes and so on. This unique technology provides an avenue for the rapid and reliable assessment of the state of a battery during its entire life cycle.
How does magnetic field affect ohmic internal resistance in a battery?
In the process of discharge, due to the action of magnetic field, the battery magnetized and many small magnetic dipoles generated, which make the granular materials in the battery magnetically arranged, improve the ion conductivity and make the ion move faster. Therefore, the ohmic internal resistance in the electrolyte becomes smaller.
