SUMMARY

Electromagnetic forces are generated by electric currents, which create magnetic fields denoted as \vec B. When there is a net nonzero electric charge, an electric field \vec E is also produced. The interaction of these fields results in forces on nearby charges, expressed by the equation \vec F = q (\vec E + \vec v \times \vec B). This relationship is fundamental in understanding electromagnetic interactions in physics.

How are Electromagnetic forces created by a current?
 
Physics news on Phys.org
The current produces a magnetic field \vec B. If there is a net nonzero electric charge, then it produces an electric field \vec E also. These fields produce magnetic and electric forces on nearby charges: \vec F = q (\vec E + \vec v \times \vec B).
