If we add the most electricity intensity of magnetic field, it will add up. In every place where there is electricity, magnetism, but just because we can measure measuring electromagnetic fields must use.
If we increase the electricity intensity of the magnetic field is increased. Wherever there is electricity, it has a magnetic field, but just because we can measure than the measure electromagnetic fields to use.
If we add a lot of the intensity of magnetic field current will increase. In the electricity, will have a magnetic field but just can be measured because more than measuring magnetic field electric machine to use
