Ampere's circuital law is given by:

Which of the following material is used in making the core of a moving coil galvanometer?

At a place an electric field and a magnetic field are in downward direction. There an electron moves in downward direction. Hence this electron.

A conducting square loop of side $$L$$ and resistance $$R$$ moves in its plane with a uniform velocity $$v$$ perpendicular to one of its sides. A magnetic induction $$B$$, constant in time and space, pointing perpendicular and into the plane of the loop exists everywhere, then the current induced in the loop is

A charged particle moves through a magnetic field perpendicular to its direction. Then

Amperes circuital law is given by

An electron of energy 1800 eV describes a circular path in magnetic field of flux density 0.4 T. The radius of path is (q = 1.6 X $$10^{-19}$$ C, $$m_e$$ = 9.1 X $$10^{-31}$$ kg)

If an electron is moving with velocity $$\bar{v}$$ produces a magnetic field $$\bar{B}$$, then

Biot-Savart law indicates that the moving electrons (velocity $$\bar v$$ ) produce a magnetic field $$\bar B$$ such that:
