HERE U GO BUDDY-

SI units related to magnetism

SI electromagnetism units
Symbol	Name of Quantity	Derived Units	Unit	Base Units
I	Magnitude of current	ampere (SI base unit)	A	A = W/V = C/s
q	Electric charge, Quantity of electricity	coulomb	C	A·s
V	Potential difference or Electromotive force	volt	V	J/C = kg·m²·s^?3·A^?1
R, Z, X	Resistance, Impedance, Reactance	ohm	?	V/A = kg·m²·s^?3·A^?2
?	Resistivity	ohm metre	?·m	kg·m³·s^?3·A^?2
P	Power, Electrical	watt	W	V·A = kg·m²·s^?3
C	Capacitance	farad	F	C/V = kg^?1·m^?2·A²·s⁴
	Elastance	reciprocal farad	F^?1	V/C = kg·m²·A^?2·s^?4
?	Permittivity	farad per metre	F/m	kg^?1·m^?3·A²·s⁴
?_e	Electric susceptibility	(dimensionless)	-	-
G, Y, B	Conductance, Admittance, Susceptance	siemens	S	?^?1 = kg^?1·m^?2·s³·A²
?	Conductivity	siemens per metre	S/m	kg^?1·m^?3·s³·A²
B	Magnetic flux density, Magnetic induction	tesla	T	Wb/m² = kg·s^?2·A^?1 = N·A^?1·m^?1
?_m	Magnetic flux	weber	Wb	V·s = kg·m²·s^?2·A^?1
H	Magnetic field strength,Magnetic field intensity	ampere per metre	A/m	A·m^?1
	Reluctance	ampere-turn per weber	A/Wb	kg^?1·m^?2·s²·A²
L	Inductance	henry	H	Wb/A = V·s/A = kg·m²·s^?2·A^?2
?	Permeability	henry per metre	H/m	kg·m·s^?2·A^?2
?_m	Magnetic susceptibility	(dimensionless)
? and ? *	Electric and Magnetic hertzian vector potentials	n/a	n/a

Other units

gauss-The gauss, abbreviated as G, is the cgs unit of magnetic flux density or magnetic induction (B).
oersted-The oersted is the CGS unit of magnetic field strength.
maxwell-is the CGS unit for the magnetic flux.
?_o -common symbol for the permeability of free space (4?x10^-7 N/(ampere-turn)²).

OOPS!!!!
I am sorry for those question marks. That's not my fault. I am experiencing this problem on GOIIT since I joined it.
