Consider a current sheet in the xz-plane that carries a currentdensity of a=1 ampere per meter of its x-width (w) in the negative z-direction (I=-wk).
Previous Question gave us this:
So the direction of b is the direction of dl x r for y=0.1,positive and converse x.
So it is in x direction, considering a square with y=+ or- o.1andx= + or - 0.1traveling along that square 2Bl=μIB=μI/2l . Whencurrent is not constant, the direction of B remains the same andthe magnitude of B depends on the value of current flowing throughthe sheet at that instant.
Current Question: Find the emf, and the direction (looking fromthe positive x-direction toward the coil) and magnitude of inducedcurrent.
Extra info: (I don't know if you will need to now this to solve,but I'm putting it here just in case.)
A square loop of wire with side 0.1m and total resistance 1ÆÃ iscentered at(0, 1, 0)m and oriented perpendicularly to the vector n= (1,0,0).
