A circular coil composed of N = 110 of closely rolled up turns of wire, has a radius R = 0.25 m. A counterclockwise current I = 3.2 A is in the coil. The coil is set in a magnetic field of magnitude B = 1.5 T. The magnetic field points to the right.
Express the magnetic dipole moment μ in terms of the number of turns N, the current I, and radius R, and use it to calculate the value of μ in SI units.

It then enters a region containing a uniform magnetic field that is directed into, and perpendicular to, the page in the figure (Figure 1). The magnitude of the field is 0.450 T. The region extends a distance of 25.0 cm along the initial direction of travel; 75.0 cm from the point of entry into the magnetic field region is a wall. The length of the field- free region is thus 50.0 cm. When the charged particle enters the magnetic field, it follows a curved path whose radius of curvature is R.
