Question

write the dimensions of magnetic field​

Answer 1

Explanation:

CGS Units

Quantity Symbol Dimensions

Magnetic field strength H L-1I

Magnetic flux ML2T-2I-1

Magnetic Induction (Magnetic flux density) B MT-2I-1

Magnetic permeability MLT-2I-2

Answer 2

We have the equation,

F=qvBsinθ

Dimension of Force, F=[MLT

−2

Dimension of Velocity, v=[LT

−1

]

Dimension of Charge, q=[AT]

Sinθ is dimensionless

Then,

Magnetic Field, B=

Velocity×Charge

Force
