- A particle of charge Q is launched at speed Vo to the right at a distance d directly below an infinitely long line carrying steady current I to the right. Find the magnetic force on the particle.QUESTION 6 Two long current carrying wires, I and I2, are separated by 2 mm and both carry a current of 8 A. What is the x-component of the magnetic force in newtons on a one meter length of one of the top wire?A proton is moving to the right above a horizontal wire that carries a current to the right. What is the direction of the magnetic force on the proton?
- When a charged particle moves perpendicularly to the direction of a uniform magnetic field, the direction of the magnetic force is perpendicular to both the direction of the magnetic field and the direction of the velocity of the charged particle. Accordingly, the charge begins to move in a circular path. Since the direction of the magnetic force is toward the center of the circular path the charged particle moves along, the magnetic force is a centripetal force (recall centripetal forces from chapter 5 of the text, covered in PHY 2010). A schematic of such motion is shown below. The "X"s represent the magnetic field that is directed into the plane of this screen. The direction of velocity and magnetic force lie within the plane of this screen and are at right angles to one another, as shown below. If a charge of magnitude 7.45x10-17C, with speed 4.66x106 m/s, and mass 7.12x10-25kg moves within the magnetic field of magnitude 3.96x10-2T, what is the resulting radius of the path…A particle of charge Q is located outside an infinitely long cylinder whose axis points out of the page on which is wrapped an infinitely long current-carrying wire with steady current I. If the particle is launched with speed Vo, determine the directions such that it experiences zero magnetic force. left or right in or out up or down the force is maximum any direction50 cm-> 10 cm 8.0 A R = 1.0 x 10-3 A small circular loop of wire of radius 5 cm and resistance 1E-3 Q is centered inside a large circular loop of wire of radius 50 cm. The larger loop, which initially carries a current of 8 A, is cut and its current is reduced to zero over a time interval of 1E-6 s. Our goal will be to find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.)
