Question 200: Magnetism and Matter

Question

Two very long, straight, and insulated wires are
kept at 90° angle from each other in xy-plane
as shown in the figure. These wires carry
currents of equal magnitude I, whose directions
are shown in the figure. The net magnetic field
at point P will be :

Accepted Answer

Magnetic field at point P
$${\overrightarrow B _{net}} = {{{\mu _0}i} \over {2\pi d}}( - \widehat k) + {{{\mu _0}i} \over {2\pi d}}(\widehat k) = 0$$

Answer

$${{ + {\mu _0}I} \over {\pi d}}\left( {\mathop z\limits^ \wedge  } \right)$$

Answer

$$ - {{{\mu _0}I} \over {2\pi d}}\left( {\mathop x\limits^ \wedge   + \mathop y\limits^ \wedge  } \right)$$

Answer

Zero

Answer

$$ {{{\mu _0}I} \over {2\pi d}}\left( {\mathop x\limits^ \wedge   + \mathop y\limits^ \wedge  } \right)$$
