The Magnetic Field Principles (Second Newton’s Law for Rotation (V (Emf)…
The Magnetic Field Principles
Ampere’s (circuital) Law
Basic of electromagnet
H = N * i / lc
B = μ
H
where μ = μ0
μr
Φ = B * A
F = Φ * R
P = 1 / R
When electric current flow, magnetic field will be produced around the conductor.
Faraday's Law
Basic of Transformer
Voltage will be induced when a magnet passing through a coil of wire, which directly proportional to change of time
Electromagnetic Force (Lorentz force)
Basic of Motor
F = i
l
Bsinθ
Force will be induced on a current carrying wire which surround by magnetic field
Second Newton’s Law for Rotation
V (Emf) =(v * B) • I
Voltage induced in conductor when it move through the magnetic field
