Two long wires carrying current I1, and I2are arranged as shown in figure. The one carrying current I1 is along the x-axis. The other carrying current I2 is along a line parallel to the y-axis given by x = 0 and z = d. Find the force exerted at O2 because of the wire along the x-axis.
This is a Short Answer Type Questions as classified in NCERT Exemplar
Explanation – in biot savart law, magnetic field B is parallel to idlr and idl have its direction along the direction of flow of current.
Here, for the direction of magnetic field at O2, due to wire carrying I1 current is B| parallel idl r or I k, but it is -j
So the direction at O2 is along y-direction.
The direction of magnetic force exerted at O2 because of the wire along x-axis
F= ilB=j (-j)=0
So the force is zero.

There are two types of electricity - static and current. The current electricity is divided into Alternating Current (AC) and Direct Current (DC). Based on the production methods, electricity is divided into - heat, chemical, pressure, light and magnetism.
