A long, straight wire carries a current of 5.20 A. An electron is traveling in the vicinity of the wire.
Part A
At the instant when the electron is 4.30 cm from the wire and traveling with a speed of 6.10×104 m/s directly toward the wire, what is the magnitude of the force that the magnetic field of the current exerts on the electron?
Part B
What is the direction (relative to the direction of the current) of this force?
opposite to the current |
in the same direction as the current |
perpendicular to the current |
Alright Dude, If that worked for you... don't forget to give
THUMBS UP.(that will work for me!)

A long, straight wire carries a current of 5.20 A. An electron is traveling in the vicinity of the wire.At the instant when the electron is 4.70 cm from the wire and traveling with a speed of 5.80×10^4 m/s directly toward the wire, what is the magnitude of the force that the magnetic field of the current exerts on the electron?
Check my work Wire with current I Electron A long straight wire carries a current of 60.5 A. An electron, traveling at 1.00x 10 m/s, is 7.60 cm from the wire. What force acts on the electron if the electron's velocity is directed toward the wire? If the direction of force is perpendicular to the current, enter a negative value.
An electron is moving in the vicinity of a long, straight wire that lies along the x-axis. The wire has a constant current of8.10 A in the -x-direction. At an instant when the electron is at point (0, 0.200 m, 0) and the electron's velocity is v⃗ = (5.00 × 104 m/s)i^ −(3.00 × 104 m/s)j^. What is the force that the wire exerts on the electron? Calculate the magnitude of this force.
A very long, straight wire carries a current of 12.7 A out of the screen. An electron outside the wire is 1.69 cm to the right of the central axis of the wire and is moving with a speed of 3.59×106 m/s. Find the magnitude of the magnetic force on the electron if it is moving directly away from the wire (i.e., rightward). Find the magnitude of the force on the electron if it is moving parallel to the wire...

4) A long straight wire carries current i = 2.0 A. A triangular loop (w = 0.050 m and t = 0.100 m) also carries the same current and is located at distance x = 0.025 m from the straight wire as shown. Recall that the magnetic field due to a long straight wire is given by B Ho 21 4r where r is the perpendicular distance from the wire. Note: Ho/472 = 1 x 10-?T.m/A. a) Determine the magnitude...
