State whether true or false :
An electric current is a stream of moving charges which create a magnetic field whose direction is at right angles to the direction of the current

True
False

From Biot-Savart Law, the magnetic field created is given by
$d \to B = \frac{μ_{0}}{4 π} \frac{(I d \to l \times^{'})}{r^{3}}$
Clearly the direction of magnetic field is perpendicular to the direction of current flowing.
