Question

plz tell me important formulas in electromagnetism​

Answer 1

Answer:

Magnetic quantities

Quantity (common name/s) (Common) symbol/s SI units

Magnetic potential, EM vector potential A T m = N A−1 = Wb m3

Magnetic flux ΦB Wb = T m2

Magnetic permeability V·s·A−1·m−1 = N·A−2 = T·m·A−1 = Wb·A−1·m−1

Magnetic moment, magnetic dipole moment m, μB, Π A m2
