Magnetism Flashcards
1
Q
Dipole antenna length
A
l=alpha/2
2
Q
Inductance formula
A
L=Vind / (I / t )
H=V / (Amp / seconds )
3
Q
Induced EMF formula
A
Vind = -B * l * v
V=Tmm/s
4
Q
Magnetic flux density on a coil
A
B=mu0 * mur * H = mu0 * mur * (I*N)/I
H=(Amp * whorls) / m
5
Q
Thomson formula for frequency
A
f=(1/2pi)(1/sqrt(L*C))
6
Q
Transformers ratios
A
U1N2 = N1U2
P1=P2
U1I1=U2I2
