A long wire is along `x = 0, z = d` and carries current in positive y direction. Another wire is along `x = y, z = 0` and carries current in direction making acute angle with positive x direction. Both the wires have current I. Find the magnitude of magnetic induction at `(0, 0, 2d)`.

Along the direction of current carrying wire, the value of magnetic field is ?

Imagine a current carrying wire with the direction of current downward or into the page. The direction of magnetic field lines is

Infinite wires, each carrying a current 0.5 A, are kept parallel to y-axis and intersecting x-axis at x=+-1 m, +02 m , +-4 m , +-8m etc. Wires kept at positive values of x carry current in the same direction while wires kept at negative values of x carry current successively in opposite directions as shown in Fig. A wire is kept parallel to x-axis and intersecting y-axis at y=2 m. It carries a current i. Assuming this wire to be insulated from others then the current i in it such that magnetic induction at O is zero is (assuming each wire to be infinitely long)

A wire of iength I carries a current along the x-axis. A magnetic field B=B_0(hatj+hatk) exists in the space. Find the magnitude of the magnetic force acting on the wire.

Let two long parallel wires, a distance d apart, carry equal currents I in the same direction. One wires at x=0 , the other at x=d (as shown in Fig) Determine magnetic field at any point x-axis between the wires as a function of x.

The direction of magnetic field at a point due to an infinitely long wire carrying current is

A wire of length l carries a current I along the x-asis. A magnetic field exists which is given as vecB=B_0(veci+vecj+veck) T. find the magnitude of the magnetic force acting on the wire.
