A proton is moving in a uniform magnetic field as depicted below. B Describe the motion of the proton if it is moving: i. parallel to the field, ii. Perpendicular to the field, iii. At an intermediate angle to the field.

A man sets up a single coil of radius R = 20.0 cm, consisting of N = 40.0 turns and carrying a current of I = 4.00 A. The situation is illustrated in Figure 1 below.Figure 1 The arrangement of the single coil as used in Question 2 parts (a) and (b).The student measures the x-component of the magnetic field (Bx) at 5.0 cm intervals along the axis of the coil (i.e. at r = 0) and records their data in Table 1. Use the data in Table 1 to plot a graph of Bx against x. Draw a smooth curve through your data points. x/cm -25.0 -20.0 -15.0 -10.0 -5.0 0 5.0 10.0 15.0 20.0 25.0 Bx/μT  124 178 261 360  462 503 462 360 261 178 124

In case A and in case B a current carrying wire is shown

A vertical wire is connected to a battery in such a way that a current flows from the floor upward to the ceiling, as shown in the bird's-eye view at right. A standard bar magnet is held parallel to the floor, with the north pole being closest to the wire as shown in the figure. In what direction is the force on the wire? Top view Current going upward toward the ceiling Horizontal bar- magnet N
