A current loop is oriented in three different positions relative to a uniform magnetic field. In position 1 the plane of the loop is perpendicular to the field lines. In positionS 2 and 3 the plane of the loop is parallel to the field as shown. The torque on the loop is maximum in

a.
position 1.

b.
position 2.

c.
position 3

d.
positions 2 and 3.

e.
all three positions.

Question 2

The boundary shown is that of a uniform magnetic field directed in the positive z direction. An electron enters the magnetic field with a velocity pointing along the x axis and exits 0.63 s later at point A. What is the magnitude of the magnetic field?
