Question

1 Wb/m2 is equal to : (A)  104 gauss (B)  4π × 10-3 gauss (C)  102 gauss (D)  10-4 gauss

In CGS system, the magnetic field is expressed in gauss.
If a charge of

1 C

moving with a velocity of

1 m / s

perpendicular to a uniform magnetic field experiences a force of

1 N

, then the magnitude of the field is

1 T

. The SI unit of magnetic field is

Wb m^{- 2}

. Thus,

1 T = 1 N A^{- 1} m^{- 1} = 1 Wb m^{- 2}

In CGS systems
1 tesla

= 1 0^{4}

gauss

= 1 Wb m^{- 2}

Q. $1 Wb / m^{2}$ is equal to :
