If current through the conductor Y is reversed in direction, will neutral point lie between Xand Y, to the left of X or to the right of Y? 

Two long parallel conductors carry currents I and 2I in the same direction. The magnetic induction at a point exactly mid way between them is B . If the current in the first conductor is reversed in direction, the magnetic induction at the same point will be

What is the effective capacitance between points X and Y?

A thin sheet of width 2a is placed in the x-y plane between the lines x=-a and x=a . The sheet is very long in the -y and +y directions. It carries a current l towards the +y direction. This current is uniformly distributed over the width of the sheet. The magnitude of magnetic fiedl at the point P(2a,0) due to the sheet is (1/n)((mu_(0)I)/(pia))log_(e)3 . Here the value of n is ______________.

A stream of electrons is projected horizontally to the right. A straight conductor carrying a current is supported parallel to the electron steam and above it. If the current in the conductor is from left to right, what will be the effect on the electron stream?

The obtuse angle between the lines y=-2xand y=x+2 is

Two infinitely long, thin, insulated, straight wires lie in the x-y plane along the x- and y- axis respectively. Each wire carries a current I, respectively in the positive x-direction and positive y-direction. The magnetic field will be zero at all points on the straight line:
