Write dimension of magnetic flux....

Write dimension of magnetic flux.

A

`M^(1)L^(2)T^(-2)A^(-1)`

B

`M^(1)L^(3)T^(-2)A^(-2)`

C

`M^(0)L^(-2)A^(-2)`

D

`M^(1)L^(2)T^(-1)A^(2)`

Text Solution

Verified by Experts

Magnetic flux `phi=AB`
From `F=BIl`,
`B=(F)/(Il)`
`:. Phi=(AxxF)/(lf)`
`phi=(AxxF)/(Il)`
`:.[phi]=([A][F])/([I][l])`
`=(L^(2)xxxM^(1)L^(1)T^(-2))/(A^(1)xxL^(1))`
`=M^(1)L^(2)T^(-2)A^(-1)`
