Using the slider on the battery, change the voltage of the battery from 10V to 2V, as shown in the pictures below. How does changing the voltage affect the magnetic field?

Changing the voltage of the battery affects the strength of the magnetic field. As the voltage decreases from 10V to 2V, the strength of the magnetic field decreases. A higher voltage creates a stronger magnetic field, while a lower voltage results in a weaker magnetic field.
