Electric field and magnetic field relationship

In summary, the conversation discusses the relationships between electric field E and magnetic field B as found in literature. The first expression relates B and E for a charged particle moving in the x direction, while the second expression relates E'_y and B'_z for a different situation, involving a pure magnetic field B_z and a velocity v in the x direction. The conversation also considers the equation F/q=uxB, and whether there is a special name for E in this case.

We find in the literature the following relationships between electric field E and magnetic field B
B(z)=E(y)V/cc
and
E(y)=VB(z)
Is there a way to define the situations when they hold?
Thanks

apparently only if v^2=c^2 for nonzero fields

Your first expression is the relation between B and E for a charged particle moving in the x direction.
Your second expression is for a different situation.It gives the relation between
E'_y and B'_z if you are moving with velocity v in the x direction with respect to a pure magnetic field (no E) B_z.

thanks. is there a special name for E' in the second case?

Consider please the equation
F/q=uxB
If I call E=F/q E has that E a special name?
Thanks.
 

1. What is the relationship between electric and magnetic fields?

The relationship between electric and magnetic fields is described by Maxwell's equations, which state that a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. This relationship is known as electromagnetic induction.

2. How are electric and magnetic fields generated?

Electric fields are generated by electric charges, while magnetic fields are generated by moving electric charges (i.e. current). They are both fundamental forces of nature and are generated by the interactions of charged particles.

3. What is the difference between electric field and magnetic field?

The main difference between electric and magnetic fields is that electric fields are created by stationary electric charges, while magnetic fields are created by moving electric charges. Electric fields also act on stationary charges, while magnetic fields act on moving charges.

4. Can one exist without the other?

No, electric and magnetic fields are always interconnected and cannot exist without each other. A changing electric field will always create a magnetic field, and vice versa. This is known as the electromagnetic field.

5. How are electric and magnetic fields measured?

Electric fields are measured in units of volts per meter (V/m), while magnetic fields are measured in units of tesla (T). These measurements can be taken using specialized instruments such as voltmeters and magnetometers.
