How do we figure out this problem with the right hand rule? At the very bottom, would the current be going right, and gravity going downwards, so the only option would be the magnetic field going into the page?
A conducting bar of length ℓ moves to the right on two frictionless rails as shown in the figure below. A uniform magnetic field directed into the page has a magnitude of 0.330 T. Assume R = 8.70 Ω and ℓ = 0.390 m. A vertical bar and two parallel horizontal rails lie in the plane of the page, in a region of uniform magnetic field, vector Bin, pointing into the page.

An electron and a proton, both with the same initial velocity, v, enter a region with a uniform magnetic field B out of the page, as shown. Each one undergoes semi-circular motion in the field and exits the field some distance d from the entry point. (The diagram shows the path for just one of the two particles.) Consider the following two statements and decide if they are true or false. i) The particle shown in the picture must be the negative one (the electron). ii) The distance "d" for the proton will be greater than "d " for the electron. В d. (shot with same v) i is true, but ii is false Both i and ii are false i is false, but ii is true Both i and ii are true

Let's consider a circular wire placed on a horizontal table between two straight, parallel, infinite wires, as shown in Homework 6 Figure 1. The center of wire 3 (P) is halfway between wires 1 and 2. If I1= 1.73 A, I2 is 3.69 times greater than I1, s = 0.35 m, and d = 1.49 m, find the value of the current running through 3 such that the magnetic field due to these three currents at point P is zero. is the current clockwise or counterclockwise?
Consider the two current-carrying wires in the figure. On the left is a long, straight wire carrying current I. In the same plane, there is a rectangular loop, which carries a current I2. The dimensions of the rectangular loop are shown in the figure, and the left side of the loop is a distance c from the wire. What are the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire?

Consider the system pictured in the figure below. A 15.7-cm horizontal wire of mass 15.1 g is placed between two thin, vertical conductors, and a uniform magnetic field acts perpendicular to the page. The wire is free to move vertically without friction on the two vertical conductors. When a 5.20-A current is directed as shown in the figure, the horizontal wire moves upward at constant velocity in the presence of gravity. (a) What forces act on the horizontal wire? (Select all that apply.) O electric force O gravitational force O magnetic force (b) Under what condition is the wire able to move upward at constant velocity?

A particle of mass “M” and charge “+Q” Travels at a velocity “V” in a plane perpendicular to a Magnetic Field of magnitude “B” as shown in the Picture. The particle will experience motion on a circular path. (not the question just context, also the pic is for probelm 1.) Assume similar conditions as problem 1 but now the proton, moves along the magnetic field undeflected. This new behavior can only be explained if there exist an external electric field in addition to the magnetic field. What is the magnitude and direction of such field? (you can disregard gravity) (prob 2 is the question:) sorry if its confusing)
