A uniform megnetic field, parallel to the plane of the paper exixted in space intially directed from left to right. When a bar of soft iron is placed in the field parallel to it, the lines of force passing through it will be represented by

A uniform magnetic field, parallel to the plane of the paper existed in space initially directed from left to right. When a bar of soft iron is placed in the field parallel to it, the lines of force passing through it will be represented by

A wire is placed parallel to the lines of force in a magnetic field and a current flows in the wire. Then :

A uniform magnetic field exists in the plane of paper pointing from left to right as shown in figure. In the field, an electron and a proton move as shown. The electron and the proton experience:

A bar of mass m and length l moves on two frictionless parallel rails in the presence of a uniform magnetic field directed into the plane of the paper. The bar is given and initial velocity v_(i) to the right and released. Find the velocity of bar, induced emf across the bar and the current in the circuit as a function of time

A uniform electric field of 200NC^-1 exists in space in the X-direction. Calculate the flux of this field through a plane square area of edge 10 cm placed in the Y-Z

A uniform electric field exists in space. Find the flux of this field through a cylindrical surface with the axis parallel to the field.

The magnetic field ofa U-magnet is parallel to the surface of this paper with the N-pole on the left side. A conductor is placed in the field so that it is perpendicular to this page. When a current flows through the conductor out of the paper, it will tend to move :

The electric flux through a hemispherical surface of radius R placed in a uniform electric field E parallel to the axis of the circular plane is
