WebIn physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields.The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in … When an EM field (see electromagnetic tensor) is not varying in time, it may be seen as a purely electrical field or a purely magnetic field, or a mixture of both. However the general case of a static EM field with both electric and magnetic components present, is the case that appears to most observers. Observers who see only an electric or magnetic field component of a static EM field, have the other (electric or magnetic) component suppressed, due to the special case of the imm…
WebWhere ϕ = force producing the field, ℛ = resistance to the magnetic flux (reluctance). The relationship between F in gilberts and ampere-turns is a factor of 1.257. This relationship is stated: F = 1.257I ×N F = 1.257 I × N. Where F is the force in gilberts, I is the electric current, and N is the number of turns.
