1. A conducting rod with length 0.5 m lies on top of a U-shaped rail that has a resistance R = 152, creating a rectangular conducting loop (see figure). The loop lies in a region of constant magnetic field B = 0.15 T with a direction that is pointing into the horizontal plane. The conducting rod experiences an external force that moves it to the right with an acceleration a = Ct2, where C = 1 m/s4. (a) Find the...

A conductive rod is placed on a U-shaped rail which are then placed in a uniform magnetic field (out of the page) of magnitude 0.500 T. The conductive rod is pulled at a constant speed of 0.500 m/s. The U-shaped rail has negligible resistance and dimension l = 0.440 m as shown in the figure. The light bulb has a resistance of 2.00 Q and the conductive rod has a resistivity of 2.00 x 10-30m and a cross-sectional area of...

A
conducting rod of mass m and resistance R, slides with no friction
on an horizontal rail of width l and negligible resistance. At t=0,
the rod passes O with a velocity v0. The rail is closed from one
side only, so that the rod actually forms a closed circuit. A
constant magnetic field B is present everywhere, perpendicular to
the plane of the rail. v0, m , l, R and B are given?

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...

Not sure if there isn't enough information since the left loop
is increasing while the right loop is decreasing flux. Or is it
clockwise? I would love an explanation.
Question 2 1 pts For our review of the second unit of the course, we'll be focusing on (1) Loop and Junction rules in circuits, (2) the magnitude and direction of magnetic forces, and (3) induced magnetic fields and currents. So think back to what you already know to answer the...

need help with this part
A conducting rod with a weight of 2.00 N and a length of 3.00 m can slide with no friction down a pair of vertical conducting rails, as shown in the figure below. The rails are joined at the bottom by a lightbulb of resistance 3.00 ohms. The rails have stops near the bottom to prevent the rod from smashing the bulb. There is a uniform magnetic field of magnitude 5.00 T directed out of...
Rod OA rotates counterclockwise with a constant angular velocity of θ = 5 rad/s
Rod OA rotates counterclockwise with a constant angular velocity of θ = 5 rad/s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r = 1.5(2-cosθ)ft. (Figure 1) Part AIf both collars weigh 0.80 lb, determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ = 135°....

In this problem, you will use Lenz's law to explore what happens when an electromagnet is activated a short distance from a wire loop. You will need to use the right-hand rule to find the direction of the induced current. When the switch is open, which of the following statements about the magnetic flux through the wire loop is true? Assume that the direction of the vector area of the wire loop is to the right. There is no magnetic...
