context: Through combining the definition of electric current as the time rate of change of electric charge, a rule of vector multiplication called Lorentz's Law describes the force on a charge moving in a magnetic field. The connection between electricity and magnetism allows for the description of a unified electromagnetic force that acts on a charge. This force can be written as a sum of the electrostatic force (due to the electric field) and the magnetic force (due to the magnetic field). Fully stated, this is the law:
question: তড়িৎ-স্থির এবং চৌম্বক শক্তি কত?
answers: electrostatic force the electrostatic force (due to the electric field) and the magnetic force (due to the magnetic field). electrostatic force (due to the electric field) and the magnetic force the electrostatic force (due to the electric field) and the magnetic force
