Give Biot - Savart formula in vector form.

A

`dvecB=mu_(0)/(4pi)(I(dveclxxvecr))/r^(2)`

B

`dvecB=mu_(0)/(4pi)(I(dveclxxvecr))/r^(3)`

C

`dvecB=(mu_(0))/(4pi)(Idvecl)/r^(2)`

D

`dvecB=mu_(0)/(4pi)*(Idvecl)/r^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Biot-Savart law in vector form is
`bar(dB)=mu_(0)/(4pi)(vec(Idl)xxvecr)/r^(3)`
