A square of side LM lies in the xy plane...

A square of side LM lies in the xy plane in a region, when the magnetic field is given by `vecB=B_0(2 hat i+3 hat j+4 hatk)` T where `B_0`is constant. The magnitude of flux passing through the square is …..Wb.

A

`2B_0L^2`

B

`3B_0L^2`

C

`4B_0L^2`

D

`sqrt29B_0L^2`

Text Solution

Verified by Experts

The correct Answer is:
C
`vecA=L^2veck and vecB=B_0(2hati+3hatj+4hatk)`
`therefore phi=vecA.vecB=L^2hatk.[B_0(2hati+3hatj+4hatk)]`
`=B_0L^2(0+0+4)`
`=4B_0L^2`
