Figure 1 is a sectional view of two circular coils with radius ?, each wound with ? turns of wire carrying a current ?, circulating in the same direction in both coils. The coils are separated by a distance ? equal to their radii. In this configuration the coils are called Helmholtz coils; they produce a very uniform magnetic field in the region between them. (a) Derive the expression for the magnitude ? of the magnetic field at a point on the axis a distance ? to the right of point ?, which is midway between the coils.
Please answer in detailed solution. I have attached the formulas and referencecs that we use. Thank you! A wire 15 cm long and carrying a charge of 400 C within 2 minutes is placed in between the pole pace of a magnet whose magnetic flux is 900 mT. If wire is inclined equilateral from the plane of magnetic field, what is the force exerted on the wire?

I just need to clarify something. Thank you in advance for helping me. so this is the question. and attached herewith, is its solution, however i do not get it why is the answer not negative? Where in the charge of an electron is negative?and how is north incorporated in the problem? Can you please explain ? Thank youuuuu i would really appreciate it. At a certain location, the x-component of Earth’s magnetic field is 6.5 x 10 6 T, due north. An electron moves westward with a speed sufficient to balance its weight. What is the speed of this electron?
Include all x-componenet and y-component calculations. Also include draings of magnetic field directions and theta with triangles.
Given the situation below; what direction would the magnetic field points be at ?
For this diagram, if each wire has current of 15A, how do we calculate the magnetic cforce imposed onto the top wire? How do we calculate the magnetic field in the center of the triangle? It would be great if someone could include the RHR stuff as well, with drawing direction of magnetic field for each point.
At the beginning of class, I demonstrated that a piece of metal (a section of copper pipe), when placed around a bar magnet and dropped, was prevented from falling freely due to a force between the metal and the magnet (note, however, that this is NOT a magnetic force). This too is a consequence of Faraday's Law. To experience this for yourself, play with the bar magnet and the copper pipe at the front of the room. First, confirm for yourself that the copper cylinder is not attracted to the bar magnet. Hold the magnet vertically, place the cylinder around the magnet, and then drop it. Observe whether the motion of the copper cylinder is slowed down because of the magnet, then answer the following questions: 12.Making use of Faraday’s law, explain your observations. 13.Explain your observations using energy conservation (kinetic energy, gravitational potential energy, energy dissipation in a conductor as heat, etc.).
Consider a straight wire in the plane of this paper and parallel to this printed line. If the wire carried a conventional current from left to right, what would be the directions of the magnetic field on each side of the wire? (Make a sketch)
