The Biot–Savart law is fundamental to magnetostatics, playing a similar role to Coulomb's law in electrostatics. It is an equation that describes the magnetic field generated by an electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. The law is valid in the magnetostatic approximation, and is consistent with both Ampère's circuital law. While Ampère's circuital law relates the integrated magnetic field around a closed loop to the electric current passing through the loop and is analogous to gauss s theorem in electrostatics

The concept used: Tangent drawn on an equipotential surface gives the direction of electric field intensity at that point. Now, when two equipotential surfaces intersect each other, two tangents can be drawn at the point of intersection. That means, we can get two different directions of same electric field intensity at that point, which is not possible. That's why no two equipotential surfaces intersect each other.

A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors (plates) separated by a dielectric (i.e., insulator). The conductors can be thin films of metal, aluminum foil or disks, etc. The 'nonconducting' dielectric acts to increase the capacitor's charge capacity. A dielectric can be glass, ceramic, plastic film, air, paper, mica, etc.

Motors are the most common application of magnetic force on current-carrying wires. Motors have loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process.
