Two long parallel conductors S₁ and S₂ are separated by a distance 10 cm and carrying currents of 4A and 2A respectively. The conductors are placed along x-axis in X-Y plane. There is a point P located between the conductors (as shown in figure).

A charge particle of 3p coulomb is passing through the point P with velocity $\overrightarrow{v}=\left(2\widehat{i}+3\widehat{j}\right)$ m/s; where   $\widehat{i}and\widehat{j}$ represents unit vector along x & y axis respectively. The force acting on the charge particle is 4p * 10^-5 $\left(-x\widehat{i}+2\widehat{j}\right)N.$  The value of x is

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.

There are four types of power supply - switch-mode power supplies, linear power supplies, linear power supplies, and programmable power supplies

According to this law, at any point, magnetic field due to a tiny current element is directly proportional to the current element length.

Tesla (T) is the SI unit of magnetic field. Tesla is named after Nikola Tesla.

The different types of magnetism are - Diamagnetism, Paramagnetism, and Ferromagnetism.
