Question
The loop below has a current as shown with respect to the central axis. If an electron is traveling along the central axis to the right, what is the direction of the force on the electron? For the next two questions explain your reasoning. Think about the context of the fill in the blank type questions. Can you explain how you came up with your answers to the following questions in such detail? 5. For the pictures below determine the direction of the magnetic field at the points specified a-f created by the currents in the wires below. Below and left is a clockwise current loop and the to its right are two long wires with currents in the direction show on the wire. Explain your reasoning. 6. The two long wires in the diagram above on the right each carry a current of 2A. What is the magnitude and direction of the magnetic field at each of the 3 points, d, e, and f? Assume the origin is where the wires cross and "d" is located at (60cm, 30cm), "e" is at (60cm, -120cm) and "f' is at (180cm, -120cm).Explanation / Answer
(4) According to Faraday's left hand rule, the force on the electron will act vertically upwards as it moves to the right direction.
(5) This can be solved using Faraday's left hand rule
a : vertically downwards
b : towards left
c : vertically upwards
d : at some angle in first quadrant
e : at some angle in third quadrant
f : at some angle in fourth quadrant
