to find the magnetic field due to a current carrying wire is given by biot-savart's law according to this law
DB is directly proportional to I -(1)
DB is directly proportional to DL -(2)
DB is directly proportional to sin theta
DB is directly proportional to 1/r^2
DB is directly proportional to Idlsintheta/r^2
dB =kI dLsintheta/r^2
please mark me as brain list.
