Solution. If this is electromagnetic radiation at the electron’s cyclotron frequency, Equation 29-5 implies a field strength of. CHAPTER 29 685.
We use concepts of intrinsic field and intrinsic velocity. Generally the electromagnetic field has two components, electric and magnetic.
In physics, specifically electromagnetism, the Biot–Savart law (/ˈbiːoʊ səˈvɑːr/ or /ˈbjoʊ səˈvɑːr/) is an equation describing the magnetic field generated by an electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current.
Whereas the velocity field w of the substratum appears explicitly in the electromagnetic wave equations, the substratum velocity w drops out of the wave and
Electromagnetic Field Equation. Coulomb's Law for the electric field holds exactly only for static charges.
Thus, the magnetic field associated with an electromagnetic wave is smaller in magnitude than the electric field by a factor .
Clearly, the magnetic force is small compared with the electric force unless the speed of the particles is high (a significant fraction of the velocity of light). A magnetic field B can be associated with the magnetic force.

Magnetism occurs when a charged particle moves with a certain velocity through space.
Recall the equation for obtaining the velocity of an object when it is dropped from a height.
