This diagram shows the magnetic field lines near the ends of two magnets. there is an error in the diagram. which change will correct the error in the diagram? a) changing the n to s b) reversing the arrows on the left to point toward the n c)changing the s to n d) reversing the arrows on the right to point toward the s

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
