The difference lies in the nature of the fields. The electric fields can affect every charged particle whether it is static or moving but magnetic field can affect it only if its moving that even not along the magnetic field lines. The force due to electric field follows F=qE and is in the direction of the field itself whereas the magnetic force follows F=q(vxB) and is in the perpendicular direction to the magnetic field and thus causes the charge particle to gyrate around the field lines. Moreover the work done by a magnetic force is zero unlike in the case of an electric force.</description>

Essentially, they are both different to a grass field. Therefore, to a horse or sheep they are both identically identifiable as not very good to eat.
To perform an experiment to test the correctnes of the observation, put a sheep and a horse each in an electric field  and a magnetic field and two control subjects in a grass field. Leave well alone for 5 months or so. The horse and sheep in the grass field will be perfectly ok, the other two will have long gone to sheep and horse heaven 
If you have any more esoteric physics questions, it&#039;s always a good idea to ask a horse or a sheep first, athough they tend to be a bit ropey on string theory, so in that case ask a cow instead.</description>

Imagine a charge. An electric field will act on that charge whether or not the charge is moving. The force from an electric field of size E on a charge of size Q will be E*Q. The force will be either in the same direction as the vector for E (if Q is a positive charge) or in the opposite direction (if Q is a negative charge).

A magnetic field only causes a non-zero force if the charge is moving. The size of the force of perpendicular to both the magnetic field vector and the velocity vector and has size
Q*v*B*sin(theta), where v is the velocity, B is the size of the magnetic field, and theta is the angle between the velocity vector and the magnetic field vector.</description>

they both are corelated .E.F present both around static charge and moving charge while M.F present only around moving charge.</description>

According to Stephen Hawking in his book &quot; A Brief History of Time&quot; the two are essentially the same.</description>

i think both electric field and magnetic field are vector field and unvisiable. But while the electric field is set up by electric charge and can efect other electric charge, the magnetic field is set up by magnetic charge and can efect other magnetic charge . There are two way to set up magnetic field: moving electrically charged particle created magnetic field, or elementary particle such as electrons have an intrinsic magnetic field around them.</description>

Magnetic is caused by moving charged particles, while electric can be around still charged particles. My teacher said that they were essentially the same thing though.</description>
