It is the pre lab working "Charge to mass ratio of the electron" (e/m). Please help me do these question. Thanks so much in advance.

1.2 The Helmholtz Coils The Helmholtz coils are the vertically oriented circular coils of wire. Current is passed through the coils, which creates a magnetic field that is approximately uniform near the centre region between the coils. Question 4: In each of the three figures below, draw the direction of the magnetic field from each coil at the midpoints indicated, given the specified direction of the current in each coil. What direction will the net magnetic field be for each? Question 5: At a particular instant, an electron is moving downward in a uniform magnetic field as shown in the diagram below. Sketch the path the electron will follow and explain how you determined this. 8 0 8 8 0 8 8 8 8 8 8 8 8 8 8 8 0 8 0 Question 6: A crude representation of the apparatus is given in the diagram below. Based on the direction that electrons are expelled from the electron gun, in what direction should current run through each of the coils to produce a magnetic field that curves the electrons in the direction indicated by the dotted line? Explain how you determined this. Hint: revisit Questions 4 and 5 if necessary. Helmholtz coils Electron Gun
