Question

1. Calculate charge to mass using Voltage=0.05V, 1T, 10^-25kg

velocity = 5 x 10^6 m/s

0.9x 10^-16 C

2. For a thing circulr coil with magnetic field mapping with permanent and electromagnets, we will be determining the magnetic constant using 2 different methods based on the same formula. Aside from implicit uncertainty, do you expect the results to be different? Explain.

3. When comparing the vertical and horizontal components of a magnetic field to the component along the symmetry axis, is it reasonable to measure onky Bz?

currend au is the the symmetry axis,2=0 (2) Consider the magnetic field of a current Carrying thin coil. Electric running through coil results in magnetic field. The magnetic field strength Br along axis (za origin point of coil in the xy plane) of thin coil is given by.

pro by dless of the (corrent electromagnets, magnetic field is oduced an electric current. According to magnetism, magnetic field, always runs from north to Southpole. regardless type of magnet. whether it is permanent or electromagneti The magnetic constant deframind by using fixed distance & varying and also by fixed current coith varying distance. shocos significant eroor: This is due to instrumental croor when varying carrent. So magnetic field strength is always proportional to book current and distance from the magnetic field. (3) B2 is the magnetic field arris (z-abrs). Magaedia symmetry is a vector quantity. So to obtain. complete representation of magnetic field at ang point in space horizontal and vertical components also (Bx By respecfirely) fic freed along need, we and B = Vexet By + B
