Question

Part A What is the magnitude of the magnetic field B? at point a in the figure? (Figure 1) Express your answer using one significant figure. B = T Part B What is the direction of the magnetic field B? at point a in the figure? Part C What is the magnitude of the magnetic field B? at point b in the figure? Express your answer using one significant figure. B = T Part D What is the direction of the magnetic field B? at point b in the figure? Part E What is the magnitude of the magnetic field B? at point c in the figure? .B= answer in T B

Explanation / Answer

At b the magnet field is along x direction and its magnitude is 4 * 10^-6

At a the magnet field is along x direction and its magnitude is 2 * B * cos =

                                               2 * 2 * 10^-7 * ( 10 / 1 ) * (1/ (2^.5)) = 2 * 10 ^-6

At c it is still same as at a
