The magnetic field is uniform over each face of the box shown in (Figure 1). Suppose B1 = 1 T, B2 = 4 T.

Part A: What is the magnetic field strength on the front surface?

Express your answer with the appropriate units.

Part B: What is the magnetic field direction on the front surface? 

Into the front surface, perpendicular to it.
Parallel to the front surface.
Out of the front surface, perpendicular to it.

Relevant knowledge

The term “magnetism field” refers to a field which describes the magnetic effect on electric charges that are moving as well as electric currents and magnetic materials. A charge that is moving in a magnetic field is subject to an angle that is perpendicular to its own velocity, and also with respect to the field.
