	A stream of electrons is projected horizontally to the right. A straight conductor carrying a current is supported parallel to electron stream and above it. If the current in the conductor is from left to right then what will be the effect on electron stream
	The relation between voltage sensitivity (${\sigma _V}$) and current sensitivity $({\sigma _i})$ of a moving coil galvanometer is (Resistance of Galvanometer = G)
	What is shape of magnet in moving coil galvanometer to make the radial magnetic field
	If a wire of length 1 meter placed in uniform magnetic field 1.5 Tesla at angle ${30^o}$ with magnetic field. The current in a wire 10 amp. Then force on a wire will be
	A current i flows in a circular coil of radius r. If the coil is placed in a uniform magnetic field B with its plane parallel to the field, magnitude of the torque that acts on the coil is
	An arbitrary shaped closed coil is made of a wire of length L and a current I ampere is flowing in it. If the plane of the coil is perpendicular to magnetic field $\mathop B\limits^ \to $, the force on the coil is
	A circular coil having N turns is made from a wire of length L meter. If a current I ampere is passed through it and is placed in a magnetic field of BTesla, the maximum torque on it is
	A small cylindrical soft iron piece is kept in a galvanometer so that
	A, B and C are parallel conductors of equal length carrying currents I, I and 2I respectively. Distance between A and B is x. Distance between B and C is also x. ${F_1}$ is the force exerted by B on A and F2 is the force exerted by B on A choose the correct answer
	A straight conductor carries a current of 5A. An electron travelling with a speed of $5 \times {10^6}m{s^{ - 1}}$parallel to the wire at a distance of 0.1m from the conductor, experiences a force of
