Electromagnetism 1 lphys1221

What is the current equation for electromagnetism?
A current (I) in a magnetic field ( B) experiences a force ( F) given by the equation F = I l × B or F = IlB sin θ, where l is the length of the wire, represented by a vector pointing in the direction of the current.
What is the formula for the electromagnetic force?
The electromagnetic force is one of the fundamental forces of nature.
It is composed of an electric force and a magnetic force.
These twos force compose the formula known as the Lorentz force formula, which is given by F → = q E → + q v → X B → .
What are the 4 principles of electromagnetism?
The operation of electric motors is governed by various laws of electricity and magnetism, including Faraday's law of induction, Ampère's circuital law, Lenz' law, and the Lorentz force.
F = q (E + v × B).
The electric displacement D and magnetic intensity H are related to the electric field and magnetic flux density by the constitutive relations: D = ε E, B = µ H.
