A charged particle is moving in a uniform, constant magnetic field. Which one of the following statements concerning the magnetic force exerted on the particle is false It does no work on the particle. It increases the speed of the particle. It changes the velocity of the particle. It can act only on a particle in motion. It does not change the kinetic energy of the particle. A circular current loop with radius of 0.100 m is located in the...
1. A straight vertical wire carries a current of 1.45 A downward in a region between the poles of a large electromagnet where the field strength is 0.585 T and is horizontal. a. What are the magnitude of the magnetic force on a 1.00 cm section of this wire if the magnetic-field direction is toward the east? b. What are the magnitude of the magnetic force on a 1.00 cm section of this wire if the magnetic-field direction is toward...
3. Fill the blanks and the Proof - J.J. Thomson's experiment to fine the charge-to-mass ratio of the tt) (25 points) electron (i.e. e/m; The first is the experiment of Joseph John Thomson, who first demonstrated that atoms are actually composed of aggregates of charged particles. Prior to his work, it was believed that atoms were the fundamental building blocks of matter. The first evidence contrary to this notion came when people began studying the properties of atoms in large...
2. A steady, uniform magnetic field B with unknown magnitude and direction exists throughR out the shaded rectangular region shown here (diagrams are not to scale). This region is planar-entirely in the r-y plane (+x is east and +y is north). The region's width (from its west edge to its east edge) is a known distance D. The region's length (from its north edge to its south edge) is 10D. Consider the following experiments, all performed with this field. Experiment...

A rectangular loop is puilled through the field at a constant speed such that it is perpendicular to the field.What is the direction of the current induced in the loop as it enters the field? going from B-0 to not 0) ??: in A. There is no current Counter clockwise C. Clockwise Loop in B VX xxx...
electricity and magnetism (2 pt) A loop of wire forming an equilateral triangle carries a steady current I. a. Find the magnetic field at the center of loop of wire forming a triangle which carries a steady current I. Let R be the closest distance from the center to the sides the triangle. b.

Q1 Problem 1. 20 Points Problem 1. (20 points) A positive point charge (magnitude 191) with mass m travels to the right at constant speed 7. The charge enters a region with a uniform magnetic field and undergoes uniform circular motion with radius Ri. After the charge leaves the field region, the magnitude of the field is steadily changed over time At (the direction doesn't change). After the field stops changing, a second, identical charge with the same speed is...
