Every electric field is associated with a magnetic field. is it true?

It's not true that every electric field can have a magnetic field associated with it. The presence of a magnetic field is typically associated with the motion of charged particles. In electromagnetism, the interaction between electric and magnetic fields is described by Maxwell's equations.

Maxwell's equations describe how changing electric fields can generate magnetic fields (and vice versa) through electromagnetic waves, but this typically involves situations where electric charges are accelerating or changing over time. In other words, the generation of a magnetic field from an electric field often requires time-varying or accelerating electric charges.

For example, in an electromagnetic wave like light, an oscillating electric field creates an oscillating magnetic field, and vice versa. However, in static or steady-state situations where electric charges are not moving or changing with time, there may be an electric field present but no associated magnetic field.

So, while there is a relationship between electric and magnetic fields in electromagnetic waves, it's not accurate to say that every electric field has an associated magnetic field in all situations. The presence of a magnetic field depends on the specific conditions and the behavior of charged particles.
