Question

2) Consider the following five arrangements of charged rods and magnets, shown below in a top-view diagram, i.e. you are looking down on the arrangements of rods and magnets. Assume that all magnets are identical and the magnitude of the charge on the rod is the same. The arrangements are isolated from each other and from any other electric or magnetic fields. In each case the elements (rods or magnets) are spaced a distance d apart. For each case, determine: a) the net magnetic field, B, at a distance half-way between the elements, at points A - E. If there is a net B field, draw a vector at each point, A - E, clearly indicating the direction of B If the magnetic field is zero state so explicitly.

Explanation / Answer

     B. No Magnetic field. Electric field is from positive charge to negative charge.

D. direction of magnetic field Is in downward direction.

E. direction of magnetic field is at an angle of 450 in south east direction in second quadrant.
