How much force is exerted by a magnetic field on a stationary charge?
Answers
Answer:
the difference between EMF and potential difference is that EMF means electromagnetic force and potential difference means the difference between the the two ends of a circuit it means the difference between the number of content of electrons and in electromagnetic force It means the magnetic force which was generated through electricity aur electricity through which magnetic force is produced in a silver ring there is a random motion of electrons although there is no flow of electricity the flow of electricity is when there is a current or the moving of electrons is too fast in a solid or ring of silver there is no much speed of electrons or electrons so electricity cannot produce aur floor two magnetic field lines cannot intersect Each Other because at a point the magnetic field lines show two directions as two tangents can be drawn through through a point which cannot be possible the force exerted by the magnetic field on a stationary charge is zero has through fehling's left hand rule we know that through a moving charge in magnetic field experiences a force
the electromotive force is measured by energy that is given to each coulomb of charge wereas the potential difference of amount of energy used by one coulomb of charge
