Now, the time to travel the length of the solenoid is / tL v = where v || is the component of the velocity in the direction of the field (along the coil axis) and is equal to v cos θ where = 30º. Using Eq. 29-23 ( B = µ 0 in ) with n = N/L , we find the number of revolutions made is t /T = 1.6 × 10 6 . 54. As the problem states near the end, some idealizations are being made here to keep

Unformatted text preview: the calculation straightforward (but are slightly unrealistic). For circular motion (with speed v which represents the magnitude of the component of the velocity perpendicular to the magnetic field [the field is shown in Fig. 29-19]), the period is (see Eq. 28-17) T = 2 r / v = 2 m / eB ....
