What do electric and magnetic fields have in common?

Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract.

How are amplitude of electric and magnetic field related in an EM wave?

Energy carried by a wave is proportional to its amplitude squared. Clearly, the larger the strength of the electric and magnetic fields, the more work they can do and the greater the energy the electromagnetic wave carries. A wave’s energy is proportional to its amplitude squared (E2 or B2).

How are the magnitudes of the electric and magnetic field related in a plane EM wave in vacuum?

But in an EM wave, the electric field and magnetic field carry the same energy. So in an EM wave, the magnitude of the electric field is proportional to the magnitude of the magnetic field, and the proportionality constant is c, the speed of light!

What is the electric field amplitude of an electromagnetic wave?

In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields. (See Figure 1.) Thus the energy carried and the intensity I of an electromagnetic wave is proportional to E2 and B2.

Are electric field and magnetic field the same?

A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space.

What’s the difference between an electric field and a magnetic field?

A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current is the rate of charge moving past a region.
